I actually lost my wallet at the Rutgers St. Petersburg Bowl a number of years back. At the airport, I informed them that I lost my wallet and did not have anything with me. They said this happens all the time with people losing their wallets on the Rides in Disney. They asked me a series of questions, where are you going?, who are you traveling with?, What is your address? when was your last flight? SSN?... etc. and then they did a full screening of everything I was carrying. (I actually got through security quicker then my wife who went through the normal procedure.)
If you are checking a bag.. this might be a different situation.
To this day I joke that if I am ever running late at the airport, just tell them I forgot my wallet.
My Wallet was actually found and turned in to the Tropicana Stadium personal, who mailed it back to me with everything intact. IF it was one of you guys that found it and turned it in.. My sincere gratitude.
