One night in the bar, the owner is lamenting the fact that business is so quiet on Mondays, Tuesdays and Wednesdays.As he moans to some of the regulars a stranger, dressed in a tweed jacket and wearing glasses wanders over and says, "I'm sorry, but I couldn't help overhearing your conversation. I'm a doctor at the lunatic asylum up the road and I'm trying to integrate some of the more sane individuals into the community. Why don't I bring some of my patients along, say next Tuesday. You'll have some customers and my patients will have a night out."Well, the publican isn't sure but the thought of more paying customers on a quiet night appeals, so he agrees.So, the following Tuesday the guy in the tweed jacket and glasses shows up with about ten lunatics.He says to the publican, "They might try to pay for their drinks in unusual ways, please just accept whatever they give you, put it all on a tab and I'll settle up at closing time."The barman has a great time selling loads of drinks and encouraging the loonies to eat chips and peanuts. The loonies have a great time, getting drunk and paying for their drinks with empty Coke cans, banana peels, used tea bags and plastic shopping bags.At closing time the barman adds up the bill and it comes to just over two hundred dollars! The guy with the glasses and the tweed jacket starts to organize the loonies ready to take them back to the asylum. Finally he comes over and asks for the bill. The publican, feeling that he's charged them rather a lot and feeling he should do his bit to help these poor unfortunate people gives him a discount."Let's call It $150," he says.The guy in the tweed jacket smiles and says, "That's fine. Have you got change for a garbage can?"
