One day a florist goes to a barber for a haircut. After the cut he
asked about his bill and the barber replies, 'I cannot accept money
from you. I'm doing community service this week.' The florist was
pleased and left the shop.

When the barber goes to open his shop the next morning there is a
'thank you' card and a dozen roses waiting for him at his door.

Later, a policeman comes in for a haircut, and when he tries to pay his
bill, the barber again replies, 'I cannot accept money from you. I'm
doing community service this week.' The policeman is happy and leaves the
shop.

A man in a bar has a couple of beers, and the bartender tells him
he owes $8.
"But I already paid you! Don't you remember?" says the customer.

"Okay," says the bartender, "if you said you paid, then I suppose
you did."

The man then goes outside and tells the first person he sees that
the bartender can't keep track of whether his customers have paid
or not. The second man then rushes in, orders a beer, and later
pulls the same stunt.

The barkeep replies, "Okay, if you said you paid, then I suppose
you did."
