A bus driver was the first to notice and actually question aloud why it sat there. None of the passengers nearby knew anything of the bag's ownership. The driver cautiously peered over the top of the bag. He couldn't figure it out. He went to seek a supervisor; two walked over to investigate, as I backed away.
The woman supervisor turned up the corners of her mouth, as if to say "beats me." The burly male supervisor gave his look see and then... Wait for it... He kicked the bag with his left boot. At this point the woman supervisor quickly went inside the hub building. She quickly returned with a 100lb very effeminate man full of apologies, who gallantly announced that the bag was his and contained a sewing machine. See?
Everyone seemed to exhale at the same time. I, however was thinking that the bus company might need a "Strange Parcel Seminar."
