when i was a youth, i had a paper route, my aunt used to take me once in a while to collect the payments. she had 2 cars, a crumby old nova, and a nice shiny cadilac. she always took me to collect in the nova, saying that it's best to let people think u don't have much, if they think u got money, they are jealous, and don't tip well or try to avoid paying. so, is this theory true? would you take the old work truck, or the mercedes to do an estimate?
