You're a barman having a terrible time trying to keep your customers happy, by serving them with beer from the pump on the wall. In true American style you have to slide the glass along the bar, and when it's empty it's pushed back to you.
Sounds easy until you realise that on each screen there are four counters with at least two customers on each. Fail to serve one and they turn nasty. You lose a life if you fail to serve, throw too many glasses or let one slide off the bar. Serve all your customers and you move to a bonus screen before being transferred to a different bar. The bonus screen is like Find the Lady but using lemonade cans.
The graphics and sound are well done and the game has the right difficulty levels. It starts hard but not impossible, and then gets tougher, so that you feel as if you have been running through the bars. Watch out for the tips left by the drinkers, and the dancing girls.
