One person attempting to hustle another will usually attempt at a reasonable amount for hustling, so I doubt he would've gone and said "$20 for this fix" because then that would just completely turn of all customers (probably) and then there would be no chance of accomplishing any hustling.

I don't haggle with everything I buy, in fact, rarely, unless I'm in China or Chinatown or China____ etc. Obviously if I'm at the local Food Emporium I'm not going to bring my groceries to the checkout and then refuse to buy them if the cashier doesn't sell me the milk for $2 instead of $3.79.

But, there are certain things to me that prices aren't/shouldn't be completely rock-solid set on, and an example is repair, or skill. Skill doesn't have market value, and if I don't think his is worth the $8 then I'll give my imput on what I think the job is worth. Thats fine if he doesn't agree, thats why I brought the bike home.

You guys have never ever ever in your life negotiated price with your car mechanic people or window repair or whatever??

Also, for people under the age of 16 (me included) where work isn't really practical or easy to find, money isn't easy to find either. I worked a minimum wage job this summer and realized that it takes quite a bit of work to gather up $8. That's nearly 2 hours of pretty intense manual labor. And I know the LBS people have to make a living too, but it goes both ways.
