I'm reminded of a helpline call I made to my credit card provider when I didn't recognise a transaction on my statement. The woman on the other end of the phone kept telling me that I'd paid "Charlie Roy" and I was sure that I didn't know of anyone (or any company) with that name.
I eventually remembered that I'd purchased rail tickets, using that card, at Charleroi Airport in Belgium ;-)
In my office someone was spelling a word out , for someone on the phone .
All was going 'well' until he got to 'G' - whereupon he said '' G for grapes ''
