Most people do not actually know that they have to tip when it comes to pizza delivery. So what's a guy to do?
Make a website, of course. It's a good site full of interesting stories - sometimes funny, sometimes sad, but mostly amusing:
She paid for the pizzas with tip and sat it down on the steps behind her. Then she told him that she lost a bet with her friends who were now at the top of the stairs looking down at us. He asked about the bet and she said that she has to show him her tits. She asked if that would be okay. Well, being the nice guy that he is, he said sure, since she lost the bet and all. So she whipped them out, tossed them back and forth a couple of times and asked what he thought. He just said pretty nice and thanked her and walked away with the sound of her friends laughing in the background.
Maybe I should start delivering pizza!
