I wouldn’t call these two PA notes passive-aggressive — just “pretty awful.”

Update: As commenter Reb points out: The “ad” from St. John’s is actually part of a Human Rights Commission campaign that’s trying to bring attention to discrimination like this; it’s not a real ad. Notice, for example, the lack of a phone number.

PLEASE DON’T PARK JAPANESE CARS IN FRONT OF MY OFFICE PARK THE DAMN THINGS IN JAPAN. I first posted this in my window in 1992. A lot of people still don’t get it. I remember one lady that got quite indignant after reading this years ago. It would be fitting for her unemployment to have run out and if you drive one, I hope that you are one of the next ones laid off. GRANT
