I took on of my watches in for a new battery and a band. Gal did a good job, took her time and was very careful. I liked her work so I gave her $5 as a tip. She said they couldn't accept tips and that she would get in trouble. I walked away smiling but she followed us and insisted that I take it back.
Kind of sad, she did a much better job than 90% of the bike shop workers I've encoutnered.
