I was at a pub recently where they had a full kitchen but no waiters. You had to line up around the bar, catch the attention of one of the super busy barmen, yell your food and drink order, pay up, then they prep your drink and give you a buzzer that will eventually tell you to go grab your food yourself at the kitchen window.

They had the guts of slapping a mandatory service tip on the bill and the machine asked for an extra tip. I was wondering what service I was actually paying for...

At this point of mal-service, I'd take an automated machine.. could not be worse really.

Or yes, avoid the experience altogether.
