I know a flight attendant, beautiful woman even into her 40s, who was working the last leg to her overnight. This one dude stayed on the plane until he was the last passenger - no other people on the plane except the crew, all of which were getting their bags near the forward galley.
The passenger walks swiftly past this FA, in one smooth motion reaches down and removes one of her pumps, holds it in both hands and sticks his nose inside, and sniffs the inside like heβs sniffing a cigar. He then drops the shoe and runs off the plane π
