"Keep the change" when change is a modest amount

[Auburngal]

At my work, we get some people who pay by cash and if their transaction comes to say £19.40, they give myself and colleagues a £20 note and say 'keep the change', We put the change (60p in this example) into one of the charity money shakers at the till.

Today, my colleague had a customer - transaction was £14.50. Handed a £20 and was told "keep the change". My colleague queried it "are you sure? You get £5.50 change". Lad, guessing early 20s just shrugged his shoulders and left.

I can understand customers putting in less than 20p in the charity money shakers. But £5.50?

Is this a thing of people don't like carrying change? Don't people have no concept of money? Getting an increase of this from mainly from under 25s.

At least the charity (Guide Dogs) benefits.

is this at a pub?

Was it perhaps meant as a tip?

I have a perfectly good concept of money. I earn reasonably well and I am perfectly capable of making a decision to leave 5.50 tip or charity donation. I never considered that I would be judged as "having no concept of money" for doing so... Christ on a bike.

A modest amount is a small amount, is that whar you meant?

I used to work in a pub and when told to keep the change it was added to the tips jar. If I frequented a business and observed them always putting it in a charity collection, I'd be inclined to donate a bigger amount. I'm not saying staff tips aren't a good cause but if you're all consistently giving it to charity instead, I'd be impressed by you. It might have been a pre-meditated donation.

Sounds like a lucrative side hustle.

Is the money for charity or tips?

if you’d been the recipient, you’d just think it was generosity rather than “no concept of money” 😆

He doesn't 'do' cash but had been given this &20 note to use?

Usually it's people who earn well, often cash, they are prepared to round it up. My partner does the same kind of thing, usually for delivery drivers though , so it's more of a very generous tip. Often I think I would have walked and pick up the Indian for £6!

We live near a shop that school kids often go into for snacks and drinks on their way to/from school. It is not unusual for them to drop change on the floor on the way out as they can't be bothered with low value coins.

He probably meant he didn't want the coin, just the £5 note. But then felt awkward when it was misunderstood. People generally say change to mean coins.

I work in a store, people tip fairly generously, often often rounding up to the nearest bill
So a $7.50 is rounded to $10.00, $16.82 to a $20
When you go above, people appreciate it, regardless of age.
