^ I completely agree with all that you’ve said as far as them likely having the best intentions, and assuming someone already paying to have the bike put back together probably isn’t too worried about $50, etc. But at the end of the day, you just shouldn’t ever charge someone more than you said you would. It’s just poor practice, and if it’s allowed, even when intentions are good, where does it stop? Maybe OP really wanted this trip so badly he made a questionable financial decision and has already stretched the budget. Maybe OP has recently learned how to repair the spoke for just such a situation, and would have wanted the opportunity to give it a go himself and use his newly learned skills. Maybe this shop isn’t shady, but if this practice were allowed, you can surely bet all of the shady ones will damn sure take advantage of it. For so many reasons, this is something that just can’t happen. It’s very poor business practice. And it would suck if a trip were delayed due to this sort of thing(though I can assure you given the bike shop on practically every block in Portland, it could get fixed in a matter of hours), but as you said, the OP wouldn’t be blameless in that situation. He is responsible for checking over his bike and making sure it’s all in good working order before shipping it out for the tour.
