So, I am a in-home technician for a cable company, and from time to time, I get tips. Generally, the people that tip aren't the "well to-do" but the people that really don't have much. I almost always politely refuse to take their money, and the almost always shove it in my tool bag or front pocket of my shirt. I am super appreciative of their gestures, I just feel bad about taking their money when they don't seem to have much to begin with. Anyhow, to the point: yesterday I was working, and got $15 in tips from 2 different customers who INSISTED I take their money. Then, my last job of the day was at a big-ass house, dude was driving a Range Rover, just got back from golfing, that kind of shit. Anyhow, I busted my ASS at this house. Their cable was FUCKED UP and I got it all working for them after maybe 2 hours. I tell the guy to have a nice evening and walk out the door. I am halfway to my truck when he comes outside and says "Oh, I guess I should give you this." and tries to hand me a $10 bill. Now, no matter what the situation, unless your job is something that relies on tips (waitress, bartender, etc.), I feel like it is just good etiquette to politely refuse the tip once. ONCE. Then, as is almost always the case for me, the customer will say something like "Oh no, I insist!", at which point I take their money and say thank you. So I do. I say "Oh, you don't have to do that." fully expecting him to insist, at which point I will take the money. But this guy just says, "No? OK. Have a nice night." and goes back inside. I was kind of stunned. Especially for a guy as well off as this dude was, I feel like it would be nothing for him to insist that I take his $10. As an aside, people with money almost NEVER tip, which to me is kinda crazy. Anyhow, my question is am I crazy for assuming that it is somewhat of a unspoken rule that when someone offers you a tip you say no once? I have always done that, and everyone else has always insisted. I never expect tips at my job, this situation just made me question shit. Also, I didn't mean to make this so long, sorry.
