That's funny! I know how she must be getting teased,it happens to me, too. I saw on the telly that restaraunts often re-use the leftover bread and butter that a patron didn't eat rather than toss it. I certainly would rather have my own "fresh" rolls and things so she and I do others a favor by not leaving anything behind that might be "reused" on the next customer.
When I heard they scrape the dinnerplate leftovers and save the scrapings for soup, though, I nearly lost it. (EWWWWWWWWWWWWWWWWWWWWWW!!!)
