What a load of bollocks!!!!!! Bar staff are as good at their job as they are boozers. I LOVE working behind a bar and in fact, if I could earn my salary pulling pints I would be a very happy girl. Yep, drink orders are down to the punter. However if I'm asked for a Guinness as the last drink of the round, I make sure that the customer is made to wait for me to pour the first two-thirds and then serve someone else before they are handed their pint. Trust me they soon learn. "Where's my Guinness??" - the best things come to those who wait ;-) It's like Bloody Marys. I've been told I make the best in the world. Fact is, I like them, therefore I know how they should be drunk. Not too tricky really.
