We saw a guy in home depot trying to steal a very expensive paint brush, he hid it under a board on the lady scanning his items. First a bit of back story, he came about 6" from hitting me with this board and then cut me off to get in line ahead of us. he kept moving the board just right so the cashier didn't see it. My husband piped up and said, of don't forget that brush there, very politely. He glared back at us like he wanted to hit my husband, who just nicely smiled at the cashier. He yelled to my husband "it's not my fault she didn't see it, it's hers!" My husband said something about how if he didn't try so hard to hide it she would have seen it and that he could have put it on top of the board to make sure she scanned it. He again yelled that it was her fault not his paid then stormed out. The lady said thank you about 10 times.
Never dinged a car, if I did and it was noticeable I'd leave a note, if no trace was left, then no. I've had this happen to me three times, 2 times with no note, once someone came into an angled parking going the wrong way and did a ton of damage, he left a note! I can't believe he did. Good thing too since the repair cost almost a grand, and this was in 1998, luckily in CA where they DON'T have no fault, which was a bonus!
