On the rare occasions that you're not working nights, the last thing you want to do is hang out in a bar. Somehow your friends don't get the hint though, so you go along and vow to be on your best behaviour. You cringe when your mate bangs on about the card minimum and try to show the bartender you understand. And when they ring that bell, you are out of there like a shot. They have a tube to catch. You get it now.
