Yeah that narrows things down

A woman came into the store today looking for a cream that a friend had recommended. Naturally she came to my counter to see if we carried it. There is nothing at all unusual about that except for one thing. The woman had no idea what the name of the cream was. She only knew one of the ingredients - vitamin K. I had no idea which product she had in mind, and when I consulted the pharmacist, he couldn't think of anything either. So I politely told the woman that we could be more helpful if she could find out the name of the item. So she gave us that one extra detail that made all the difference (NOT!) - she said "It comes in a tube." Yeah, that narrows it down to only 3 or 4 thousand products....... What the f*ck is wrong with you?
