If 1gil is too low an amount for you when you say you don't want anything, then you do want something.
You know what, you're absolutely right... I do want a few things; common decency, courtesy, and (to quote Aretha Franklin) R-E-S-P-E-C-T.
The problem with 1gil, to me, is that it is them saying:
"I don't want to pay for your time, effort, or mats. I don't appreciate you or the skills that you have put time and effort into developing... and really, I'm probably doing YOU a favor giving you a chance to get a whopping 15 Sp for your little 'craft'. I would put 0gil but the game doesn't allow it."
If you have ever waited tables and gotten a 1 penny tip (especially if you gave that table really good service and they shouldn't have had anything to complain about)... it's about the same thing.
It isn't about me getting X amount of money, at least for me. And I have done repairs for 1gil... but it was for people in my parties and I told them to put it on their bazaar for 1gil, because I wanted to offer the repairs basically for free. Like I said, when offered, I usually turn down payment for whatever favor I do for someone... but if not a matter courtesy, then at least as a recognition that you are doing them a favor, they should make the offer.
But the people we are discussing here are actively trying to NOT offer any compensation at all. More or less, they want it for free.
I was raised to believe that freebies are something offered, NOT asked for, to do so is rude and disrespectful.
If you were raised to believe something different, that's fine... but please don't infer that just because some of us won't do repairs for people who expect it for free (in effect) that it is because we are greedy or that our intentions are less pure.
