I am with another airline and that made me remember one time while boarding a flight..I was helping the Lead up front with pre-departures and a little older lady gave me what she thought was someone's ticket the man ahead of her had '
dropped' in the jetbridge. it happened to be a baggage check tag from the gate, apparently from a gentleman's bag that was right ahead of her...for some reason just ended up torn off his bag and right onto the jetbridge floor! (imagine that)
he was determined to make that oversized bag fit in the bin, even though we had already told him by just looking at his bag it probably wont fit when he came on!
he ended up coming back up to first to 'check' the bag..the Lead asked him if he would like the baggage tag he left in the jetbridge or new one..
Bless her heart for finding that tag..
