The next unexpected was of a much brighter kind. An angel in the parking lot, disguised as a masked senior, told me my left front tire was looking soft, but not to worry. He would take care of it. And so he did.
Using his pressure gauge, he determined that the tire was five pounds lower than what was recommended on the sticker inside the door, and since he just happened to have a portable air compressor as well, he was able to inflate the tire for me.
