As it turned out, even coffee was far too long to be in this man's company. He talked non-stop about himself, how rubbish his life is, how he has too work too hard (don't we all?) how terrible his ex-wife is, (you married her, get over it), how he has no friends (fancy that).
You get the picture. I ran screaming out of the coffee-shop. No, actually I drank my coffee very fast and said a polite goodbye. He was still talking at me as I left. He may still be there now.
