About the stickers to put on bikes when you repair them.... I've had that happen to me, and I wasn't chuffed about it, especially as it was a real b***** to get off. If I were to buy a new bike from a shop and they put their sticker on then that's a bit more reasonable. Bob jacksons put one of their stickers on my caygill when they repainted it, and I would try and take it off but don't know if it will come off cleanly. People with BSOs might not mind, but someone with a half decent bike might take offence at you putting a sticker on it without asking!
