Customer in Tim Hortons coffee chain:
 

EXTRA LARGE PROBLEM
The high-priced executive who came up with the idiotic plan to change the size designations of the Tim Hortons coffee cups should spend a few hours in a typical Timmys' outlet and listen to the following conversation over and over again:
Customer:"I'll have a large double-double"
Server:"Is that the new large size or the old large size?"
Customer:"Huh?"
Server:"Well the old large is now the new medium, and the old extra-large is the new large, so which do you actually want?"
Customer:"Forget about it".

I phoned up the gentleman who wrote this letter in our local paper and congratulated him for his great contribution in terms of humour.
