In Britain, people who serve in bars are just given a training session that consists of pulling one pint and then being left to get on with it.
Drives me nuts waiting at a bar and the bartender not having a clue who's next, it causes arguments if you get served before someone who THINKS they've been there longer than you.
It's not my job to know who's there first
In other countries it is more of a proper occupation rather than something students and young kids do to earn a few quid
I was in Ireland recently, the pub was packed and the guy behind the bar was serving three people at a time, getting each order correct, getting the change correct and pulling each drink perfectly.
Then when passing our table with 12 people sat around it he said "Same again for everyone is it"
He then brought the drinks over and moved to the next table, some of his colleagues were doing the same whilst one or two stayed behind the bar to serve those that were stood
It's difficult to get served in my local if there's more than seven people in it, and if seven more walk in there's a good chance they'll get served before you because they haven't a clue
