A big shout-out this evening to Mary B., at gate B3 at Midway, co-worker at the same gate and the crew at gate A17 (flight from SLC) Wednesday evening, June 13th. I left my wallet on the previous flight at gate B17. I was going to a connecting flight to Charleston, SC when I made the discovery. Mary called the gate, they responded quickly, they had my wallet and I made my connecting flight. Great teamwork, integrity (the wallet could have easily come up missing) and willingness to help a traveler. It made an impression on me!
