Wanted to change the coolant in a couple of my cars so picked up some last Saturday at AA (on sale.) Went back on Sunday to get a drain pan and some misc items. While there with my 13 year old son, one of the associates starts fussing about breaking a piece of plastic while replacing a headlight in a GM product and it was going to cost $100 for AA to fix. No real problem except he used some inappropriate language right there in the middle of the store with lots of customers (and my son) milling around. Totally unprofessional. Later that day, I went back for some tubing to assist with the coolant draining. (I had some tubing for one vehicle but of course it would not fit the other.) So when I went back, this same person says "Are you back again?" with a real snotty attitude. Almost walked out, but went ahead and got the tubing as the next auto parts store is another 20 mins away. I know its just one person, but I won't go back to that store unless its an emergency. I also believe this guy may be a manager as he is who signs off on returns and who the other associates ask their questions to. Very disappointing as I generally like AA.
