This is an old joke, actually. The first Euro trip I did was with a bunch of kids from our high school theatre, and we teamed up with a group of rowdy Canadians for much of the trip, meaning we shared transport and rooms with them.
And let me tell you, everything you suspect about Canadians getting treated better than Americans overseas (expecially in France) is true. The Brits and Canadians, in fact, like to put patches of their country’s flags on their backpacks, just to make *sure* they aren’t mistaken for Americans.
Try finding an American flag on a backpack.
So the big joke among us theatre kids at our toga party in Rome was that next time, we’d slap a Canadian flag patch on our backpacks and go, “Eh?” a lot.
I need to try it during next year’s trip to Glasgow.
