This whole thread is not only a comment on what seems to be going on at the ground, but bars in general. I've done my fair share of bar work, in various positions. What used to be considered a quiet bar, easily dealt with by one person (knowing the prices; cash only; being able to work out the change; being able to serve more than one person at a time, etc, etc) now has you stood at the bar for what seems like an eternity. Customers themselves often don't help. Figure out what you want before you try to get served. Use cash (it is still legal!). I've lost count of the amount of times I see a bunch of blokes walk up to a busy bar, do their best to get served out of turn and, having managed to do that, spend 5 minutes saying "right, who's having what?" When I was doing bar work, my immediate retort would be, "tell you what lads, when you've figured it out, I'll get back to you. Who's next?"
It's a joke these days. I got out of it years ago. Stupid itemised tills, bloody coffee, and everyone wanting to pay by card. You don't need bar staff any more, just drones.
