I've got four people deep, twenty people to my left and right. I have got six drinks at one time, turn around I have got two credit cards going. I have got people screaming at me left and right. There's nothing worse than a customer not being prepared. "Alright, sir, your total is thirty dollars." Here. What am I supposed to do with that? Not only do I not have time to sit here and uncrumple your little Rubik's cube worth of money, but it's insulting. However, people don't think about these things. You might as just well chuck it at my forehead. The way you keep your money is a direct representation or reflection of how you keep yourself in your world. If your money is crumpled up in your pocket like that, I can't imagine what your apartment looks like. You know, nice, straight, crisp bills. Here you go. Don't give me crumpled up dollars. I don't want wet money. One, two, three, thank you sir, I really appreciate that, I hope you enjoy your drink. Definitely come see me, I'll hook you up next time.
