I brought a bicycle part here, to be measured ---- as I not had the tool for measuring in my home. Once I came here to PBS La Mesa, the 1 of 3 personnel grabbed my part, and took it in the back (shop.) In the same --- that one not be assured that one's Original Part be the returned part. Of the same size. Once I re-installed the part, at home, it worked out. But still, PBS did it in the unethical manner.
