did some lawn renovation for some nice people last fall. they called back for trimming. we go out yesterday, explain that we charge hourly for this service, she says no problem. we spend 4 hrs trimming, and picking up clippings. i hand her a bill for $300. she looks at me and says, "bobby dear, you are way too cheap! the last guy charged me $600 for the same job. " she hands me $450, then an extra $20 bill for lunch she says. thats a $170 tip! i almost pooped in my pants. first off i couldnt believe the other man charged her 6 bills, then i was just shocked at her generousity. unreal. very nice people. anyone else ever get big tips?
