Re: @Doctor Syntax -- Slugs
Did a stint washing up in a restaurant (for a friend) and was told not to throw away the shells as they would be reused. They used to buy shell-less snails from the suppliers, cook them and stuff into the shells. (Surely a snail without a shell is a slug???)
Anyway, a few years later in a posh restaurant relaying this story to a colleague who had just ordered snails - managed to put him off eating them!
