Here is my newest peeve.
When I go to the bank with my weekly US checks, I habitually purchase Canadian dollars so that I can pay my bills, live my life, etc... ok?
Recently, I get the same damn comments every week from the teller at the bank... "Oh are you sure you want to exchange that currency? The rate is really bad..."
or
"OH... that must hurt..." or something to that effect.
Dear bank tellers: I FUCKING KNOW OK? You don't have to rub salt into my wound each and every time I go into the bank!

Thanks.
