I knew two brother-in-laws who were both tradesmen yet very different in size. The smaller man was 5'7" and average build while the other was 6'5" and when he stood in a doorway, he filled it. He wasn't fat, he was just muscle. They had a conversation about customers who were slow to pay.
Small tradesman: "It's so difficult getting money from some people. I go to their home and ask to be paid and they give all sorts of excuses assuring me. Yet nothing usually happens and another visit and more excuses.
Large tradesman (with a surprised voice): "I don't have any problem. I knock on the door and just say I want my money. They simply pay up."
