I can't really make sense of what could/should have happened with regard to arrests and such because it's all pretty much wrong!
For a start we work closely with the police, and every month there are meetings where the council licence bods, police and pub folk meet, I am in a city centre rather than a village pub, but still, we know what the police are looking at (underage, drugs etc) quite frankly they all but tip you off that they are running certain operations.
In real life you can get temporary event notices to vary the trading hours REALLY easily and they don't cost a lot. We put in for them to serve alcohol early for events like football matches. It's literally send a form by email to council and police.
In real life I know of people who operate clearly outside of their hours and police don't seem to act to be honest, it's not that big a thing from what I've seen.
If it was in my pub, and I had done it, I would expect a call from our licensing officer and that they would come in and see me, in plain clothes, having told me they were coming. I don't know for a fact without looking it up and I don't have time to do that, but I may be arrested or not, not sure about which member of staff would be as well. I would think I'd be bailed it's not like is a major crime. Unlikely to go to court the next morning. I shall ask the police next time I see them!
I know for some things both the dps and staff member get penalised, we make it very clear when training staff for example if you are caught serving underage, the member of staff gets a £50 fine and the dps up to £5000. So in some situations the staff are also liable, hence Barstaff now needing personal licences, but to be honest it's that long since I did my training for licences I can't remember!
I have to go to work now but I'll try and make sense of it when I get there.... maybe ask some more responsible grown ups who work for me if they know!
And the name above the door thing, I remember when the carters did it, it was wrong then. I've been in the pub trade for 20 years. I looked forward to the day I'd have my name above the door. I got the bloody pub, and when I asked about it it was no longer needed, but some still do it, but I was strongly advised not to. So I didn't and I'm still bitter. All those years for nowt! It's a different trade completely to how it used to be. So much red tape, so many courses, it's a pain in the backside for the most part and if I wasn't so long established it wouldn't be viable.
