I had an offer from a large company and they offered to fly me out to the
meeting on business class.  During the return flight we were given gourmet
brownies and cookies. Not hungry, I decided to save them for later, so I
placed them in a vomit bag. 
 
After the plane landed I got up to leave and a stewardess approached me. 
 
She asked, "Sir, would you like for me to dispose of that for you?"
 
I said, "No thanks, I'm saving it for my kids."
