As a lift operator myself, you tip $100, lol. Na most don't tip at all, there are a few that do, But it's in the range you posted. Most of our crew don't expect one so it is nice to get one. Each person on the crew gets the same tip, if someone gives me a $100, I split it equally to all crew members, and end up with $10 bucks myself. But we have a large crew, and haul small stuff, up to 150 tons.
