Although I am not a politician, I think I would have to agree with BOTH sides in this issue. If the OP was complaining about rude treatment, then I think he has a valid point. The "enforcer" could certainly been more "gentle" in telling him that the parts department was indeed closed that day without insulting him. However, the dealership was also correct (in my humble opinion) in not making an exception in this case. I have worked in retail many years ago and remember the times when a potential customer came in AFTER closing hours and wanted service. On the other hand, I had been there all day and was ready to go home and be with my family like everyone else. If this had been some kind of emergency situation that changes everything, but in this case it could have waited. Bottom line is, both sides could have handled it better with no hard feelings.
