This shit! I work at a bike shop and people really don't get a liability stand point or the fact that the tool they asked to borrow cost a few bills. Best is the idiots who think "just a little lube, and air and it will be fine" or the "just give it a once over" assholes. No dumb ass, I can't just give it a once over, you get a damn tune up because it takes me time to do the "once over" and call you to tell you your bike needs this, and this.
I hate customer service.
