Here's a clue from a book of Daily Mail cryptics. It says :
Ate out with unhappy waiter losing heart and not present (6).
According to the answer at the back of the book, it is ETCHED.
Can anyone decipher the clue? I can normally decipher them once I've got (or seen) the answer, but I don't even know where to start with this one. I'm assuming its not a misprint. Thanks
