The manager dented my car while he was inspecting a trade-in. When he opened the trade-in's door it whacked my car. I saw him do it and he said "oh it's mostly plastic it wouldn't have done any damage". No "sorry", no contrition, just arrogance. When I checked, there was definitely a small dent. Too small to ask them to fix, but definitely there. An apology would probably have been appropriate.
And if that wasn't enough - we found the sales people hard to engage and pretty dismissive (probably because it was 20 minutes from closing and they figured they weren't going to make a sale from us in the short term).
