Mobile Rv tech-warranty work-do you guys tip????

I don't tip my local mobile guy. But then again, none of my work so far has been of an emergency nature. He worked me in as his schedule allowed. However, if he came out on a Sunday morning to our site to fix an urgent problem, that would be different.

One thing I do is throw him some of my parts and supply business. I buy my caulk through him, have bought a fridge roof vent, control module for the water heater, etc.
