Usually it's people from Canada ("Snowbirds") who come down here to complain and find fault with everything they can, so my first assumption is that the so-called victims are from Canada or the northern tier of U.S. states that have learned to act like Canadians.
You never want to be behind them in the check-out line at a supermarket or you'll quickly learn how these people act when on vacation with a lot of time on their hands.
They do nothing but complain and nit-pick about every little thing. Then they get on our highways and drive 8 mph in a 45 mph zone. They especially love to do this when it's on a narrow highway so that you can't pass them.
The free enterprise solution to their problem is to use your wallet and take your business elsewhere. It is not necessary to sue everyone that displeases you.
I refuse to patronize the local McDonalds for a different reason. They are the slowest McD's in the world...but then that fits in with the Canadians as they have an affinity for slow.
