One morning, a Hell's Angel goes into a coffee bar and orders a large cappuccino. As he is about to leave, he asks the waitress for his bill.
"Two pounds sixty," she says.
The Hell's Angel produces 260 penny coins, drops them on the floor and leaves.
This happens every morning for the next few days until one morning the Hell's Angel wants to pay with a fiver. Gotcha, thinks the waitress, who has been waiting for this day to get her revenge: she drops 240 pennies onto the floor.
"Your change," she says with a smug little smile.
The Hell's Angel produces a 20 pence coin and places it on the table.
"Another large cappuccino, please."
