I guess some stores are like that, I worked at schwab about 5 years ago and never had or heard of it happening, though I only worked in tires for 2 weeks.
it took walmart an hour and a half to get 2 33's mounted on old wheels i had for a freind, when they were finally ready to pick up, they had wheel weights all the way around the back of the wheel, i asked why and they didnt know...
wheel was bent. (they couldnt figure that out after ten minutes?)
wallys wont wipe the water out of the tire either, which pisses me off.
