I remember my son (about 12 years old then) and I going just across the border into the USA, about two decades ago, to watch the Sprint cars in action. The races were great and just before my son and I left to make the night journey home to Canada, we stopped off at a McDonald's to get a bite to eat. We ordered our food and the serving lady asked if we were Canadian.
I replied yes we were, but how did she know ? She said....' well you paid for your burgers with that Canuck funny money and that's always a tip off.
'
I'm just making that part up.
We paid with American dollars.
She really said, that she could tell we were Canadian because we ordered by starting our order with 'please' and ended it with a 'thank you.'
She was right, and I know over the years many can tell a Canadian by our sometimes tendency to overdo it on politeness.
Thank you,
Les
