On the way to the doctor's office, an SUV in front of us had a bumper sticker that read, "Beware of Dog."
Really? Was there a dog on board most of the time which passers-by should beware of?
Then, at the doctor's office a sign on the front door said, "Beware of Dog." We did not see any blind folks. We did not see any work dogs.
Apparently dogs have become ubiquitous in society.
By the way, neither sign had quote marks. I only used quotation marks to quote the signs.
