I know what a Happy Hour is LW - my point is that any "elderly man" could sit in any of these downmarket Sunee go-go bars (I've never been in Winners) with a bundle of 20B notes and carry on as you have described at any time they're open - it's not restricted to a certain time frame

Unless of course you prove me wrong by posting a pic of a sign outside e.g. Nice Boys saying NO 20B WANKS BEFORE 8PM/AFTER 9pm
