My only real accidents have been:
Dropping my BRAND NEW Teal Little Darlings piggy vial on the bathroom tile, and breaking it. I never even got to use the damn thing.
I got some chips here and then while depotting my e/s, but nothing major.
A coworker of mine was telling me at work tonight that she had her makeup bag in the locker room at work, with about $500 of MAC (she has a Pro card) in it, and someone stole it.
Considering where I work, and the fact that you have to pass a background check to be employed there..knowing that I work with thieves is disheartening.
Having said THAT...I would NEVER leave anything of value laying around. She should have kept it in her soft locker, or something. But having stuff stolen still sucks ass.
