One time I had a can of Potato soup (Campbell's) and it was rather old, when I opened it, it was almost solid. So I threw it out even though it smelled fine just didn't want to risk it.
And I am with GingerK - the antibacterial soap is not really a good thing.
Also I swear things change in the cart - can't tell you how many time I have tried to buy dry roasted peanuts and got home with honey roasted.
