mistaken identity
i cycled down to my local chemist to pick up some drugs. i haven't been on a bike for at least 2 years so it was very exciting.
I asked for my prescription in the pharmacy and confirmed my name. whilst they nipped out back to find it, an elderly gentlement with a neck brace and no teeth said, in a very gummy way, "you have the same surname as me". he had just asked for his prescription too.
i could see some comedy mix up was possible. luckily for me (and unluckily for you the reader) the inevitable mix up did not occure and was therefore not inevitable after all.
and this whole story is a bit boring. sorry.
