Servers - yes
Bartenders - yes
Take out - most places yes, really depends
Uber - yes, but via the app
Trash guys - yes (did several major home projects last year so there was much to discard)
Roofers - yes (they roofed in 20 degree weather a week before Christmas - owner no tip, 9 workers $20 each)
Lumber yard - yes (especially the guy that does the finish cutting as he will give me buckets of scrap wood for fires)
Mailman - lol, no
Balding, so haven't needed to tip a barber in 20 years and have never paid to have a car detailed. Two possible tip-worthy occupations I just do myself.
