Ha, reminds me of the days when I was The Pizza Guy. Once I delivered a pizza to this big, multi-million$ house up on the hill. The guy pays me with a check then realizes he doesn't have any extra cash for a tip. He tells me to hold on a minute then comes back and tells me "sorry, I don't have any small bills, will this do?" and hands me a fat joint of incredible weed. Needless to say, I always made sure he got his deliveries first, hot and fresh, from that point on.
