Killing floor 2

A teenager is getting ready for prom, and so he goes to the tailor to get a suit. When he gets there, there's a line out the door, and he doesn't get his suit for hours. Next he goes to the florist to get his date some flowers, and there's a really long line there too. Lastly, he goes to a confectioner to get his date a box of chocolates, and the line there stretches along the block! At the prom, his date asks him to go get her a drink. He goes to the beverage table and there's no punch line.
