Would you do this?

[ShouldIWouldYou]

Name changed. This has been bugging me since Saturday night. I work in a bar a couple of nights a week. Saturday night was the busiest I've seen it. People were ordering 16 drinks at a time at one point. There was me and 2 others working (A&B).
The following things aren't particularly relevant in my moral dilemma but it's worth a mention:
I work another part time job, have a mortgage, a 1yo and 4yo.
I'm on £10.50 an hour at the bar. I have only been there a month.
Colleague A is on £11 an hour, works full time elsewhere and lives with parents.
Colleague B is on £11 an hour, works full time elsewhere and has a mortgage of their own with a lodger living with them.

There is a rule at the bar that if someone offers you a drink you can either have it while you're working or you can charge an extra £5 and take the money as a tip. We write these tips down on a note pad by the till and take our totals at the end of the night (these are not shared between all staff, you take your own).

Saturday night it's me, A and B working together. As I say, really busy! A is drinking and popping to the loo every so often. Not paying for drinks. B isn't drinking and neither am I. So I'm already on the back foot with A and picking up some slack.
Anyway, a huge fight broke out in the bar. No security, I handled it and managed to get everyone out. We then had to close early to clear up all the broken glass and crap people had left. This was mainly me as A was pissed and B was still serving and talking to some guys at the bar about the drama. So I'm already pissed off as I'm not paid enough for this shit.

So here's where I'm really wanting opinions on what you'd do...
A made £100 in tips Saturday night. Every time they took a big order they were adding £5/£10 to the bill and taking the money. Customers didn't notice obviously but A was NOT offered these drinks. A was just adding it to the bill and made £100.

I made £29. Because I wasn't taking money that wasn't offered to me.

What would you do?? As I'm left thinking 'I want £100 in tips!' But it's stealing isn't it? What do you think?
A can do what they like, it doesn't bother me but it is bugging me that one is walking away from the same shift with that much more than the other!

Please help sort my moral compass out, thank you 👍🏼

What is there to sort out? A was stealing. If you want £100 too you could start stealing? There's no dilemma here.

@Popdrop I agree, I see it as black and what as that but A is so blaze about it I'm sure they all do it. I'm not a thief

Not a thief though!*

What A did was theft, don't bring yourself down to their level.

Everyone's back story, finances and wages are irrelevant here.

A was stealing and I personally would report this to the manager. Not only is it illegal, it's putting you in a very dodgy position. What if a customer comes up to you and asks why an extra £5 has been added onto their bill? You either have to lie or fess up and either way, it'll cause problems.

I worked with someone who used to add drinks onto bar tabs for them to drink and help run the tab out faster giving them a higher take-per-shift total.

I would also question the ability to drink on shift. I worked in hospitality for years and years as everything from bar backer to manager. I have never worked somewhere where you were allowed to get pissed on shift. Have the odd drink with a customer? Sure, but enough to get pissed? Absolutely not.

Were there any managers on shift? Who has the licence?

A is a thief and if the punters cotton on will ruin the reputation of the bar. This needs addressing with management. Equally being bought drinks in my day was a glass of pop not an alcoholic drink

IME the standard practice is if someone buys you a drink, you either get the cash or you print off the receipt and claim your drink at the end of your shift (or at least before the next stock take)

@CatamaranViper I did say it wasn't relevant, I guess I was trying to justify why it's been bothering me so much.

Exactly what happened when I worked in a pub years ago!

@CatamaranViper B has the licence, myself and A are being put through ours.
It's a strange culture down there, never known you to be allowed to drink on the job, it's a 'as long as you can do your job' attitude. The owner is never around and the manager has run it for years and does the same.
A isn't open about what they're doing but I could see it myself and at one point said 'I'm adding a fiver on this for me and you'

This has the potential to turn into a social media shit storm for the pub.

If I was a customer I'd be really annoyed with this. Drinks are expensive anyway, and if the barman/maid was adding £5 or £10 to the bill then that is overcharging and stealing. They need something saying to them. I wouldn't want to drink there in future.

@Dinnerfor8pm no one gets itemised receipts, if a bill is coming to 50 odd pound no one is noticing the extra £5. It's a stop before the club type bar where everyone has had one too many already. A is clever with who they do it to.
I won't be doing it. You're all echoing my thoughts on it, it's just simply theft. I sound stupid as what else could it be but like I say A is so casual about it!

I'd shop A and find a better paid bar job. £10.50 is a joke, especially as you're on less than co-workers doing the same work.

Will the manager care if they find out? Did B know? Assuming they have the licence they must hold some responsibility over the bar?
