21.) I remember a friend of mine, who was working part-time in a shoe store while he was going to university, who told me this story about a cheap ass customer.... ...My friend stared at the card in silence. He finally looked up and said to the cheap ass MOFO in a loud voice, "Sir, you are a doctor. You make more money in one year than what I make in five or ten. You asked me for a pair of $4 shoe laces which I decided to buy for you to keep you happy and to shut you up. I'm spending $4 for shoe laces to give to you when I'm only earning 2% commission for selling these shoes to you. Right now, I'm $2 poorer than before you came in. YOU SHOULD BE FUCKING ASHAMED OF YOURSELF!!" I trust your friend has since learned a lesson from this.
