[Rosie] I believe I've spoken on this matter on another site, but the crux of the matter is that I'm with you on this one. My pub is licensed until 1am on friday and saturday, but I close at 12. Customers need consistency, and they need to know where they stand. On very rare occasions, I will stay open until 1am, but that is for the likes of our football team's annual prizegiving, and they all know in advance. They tend to leave about 12.30 anyway though. If the pub has 50 customers one friday night and you stay open the extra 30 minutes, what happens next week when there are 45 customers. You make yourself an immediate target for bickering. If you going to take punitive action, may I suggest you let the gaffer know before you do so, as he may not notice. He also might be more likely to change his ways in advance of losing custom.
[Rosie] Your other question. No, there is no variation in cost that tallies with what your licensable activities are. You do, though, open yourself up to a much bigger can of worms in the matter of your neighbours and their potential objections.
(Phil) I think the manager may have seen sense, though not through customer persuasion AFAIK, because there is now a completely new regime after less than a fortnight of this arbitrary stuff and the pub now has a 24-hr licence all week and is advertised (in the bar) as being open from midday to 11.30 a.m., the half-hour closed being apparently to put a few things in order each day. There is no mention of management discretion on the notice. Does this mean I can stay there drinking, probably alone, until 4 in the morning (say)? What on earth is the point of that because Carshalton is not exactly Soho. I'd like to know what's going on but the barman (not the manager) couldn't help, or wouldn't.
