^^ easy, treat them as they were your friend.
Buy them lunch, buy their kids something silly at wally world. Buy them a case of beer. They fix up your car like its their own. You pay the labour and parts.
You gain a friend, and someone you can trust.
easy as changing oil or making peach cobbler.
Also, communication goes both ways, not jus flapping your lips, but you have to attentively listen. You have 1 mouth and 2 ears for a reason.
