I get tipped occasionally, but more often than not I think that people here in Utah are not big tippers in any areas. I don't expect one and when I get one it's a bonus!
In a very rare instance I feel that a tip would have been "proper" and did not receive one. Example..... I got a call 8 am Sunday morning (I ALWAYS answer my phone) from a woman with an "emergency". Someone vomited all over over the back of her Tahoe and she could not even get in it because of the smell. I usually don't work Sundays but was there in a few hours and cleaned the truck til there was no evidence of the mishap. It was really gross. Now... she paid what I quoted her and was happy with the job, but in this instance I feel that showing up on Sunday morning w/out an appt. to clean vomit should have been more appreciated, ie: a tip. I was happy for the business and got paid for my time and I would never hold it against a customer for not tipping. But just between us here in this forum, I felt that even a small tip would have made it better.
I am sure that she had spent the bulk of her money on whatever alcoholic endeavour that produced that vomitous episode. I agree that a tip was more than called for in that instance.
