I once exchanged glances over breakfast with an obese Scotsman.
I think he was about to introduce himself, but I instinctively struck up a conversation with a Spanish waiter called Brian in order to avoid him.
I think he got the message.
That was the last glance we exchanged all week, although I did overhear him tell his wife that I was probably a little clammy in and around my novelty latex codpiece.
Even that was made in Hong Kong.
