I want a cup of coffee

A Rabbit walks into the bar, goes up to the bartender and says, "I want a cup of coffee.” The bartender says, "We don’t serve coffee here"
So the Rabbit leaves, but when he leaves he sees two friends entering the bar so he joins them. His friends ask for a beer and sandwich but the rabbit says "I wanna cup of coffee"
The bartender says, "We don’t serve coffee here"
So the rabbit leaves again, but he sees two more friends so he joins them in the bar. His friends order a beer and a sandwich but the Rabbit still says, "I want a cup of coffee"
"Look,” says the bartender "we don’t serve coffee here. Now leave or I will nail your ears to the bar!"
So the rabbit leaves, but he yet again sees two more friends and enters the bar.
But this time the rabbit says, "Do you have a hammer?"
"No" replies the bartender
Do you have any nails?"
"No"
"Then I want a cup of coffee"
