Someone explain to me this!

Couldn't agree more...it takes time, product especially if you're using quality test kits, and employee time. I own a small LFS....we were doing it allllll the time for one customer that was totally taking advantage of my staff....and taking advantage of my time and energy with using me to ask about product then buying it used from here or other buy/sell places.....it was a bit much and really drove me crazy...but my staff and myself just want to help people out...sometimes it never pays off.
