The one encounter I had was the first business trip I took, I place full blame on my employer for not letting me book the flights and giving me a 38 minute Monday morning connection in ORD. It gives me an interesting story so I hold no grudges.
I was on a CRJ flight in and the had to circle for about 20 minutes. I managed to get to the gate just in time to see the door closing so I yelled "is this still Milwaukee?" Got an odd look from the GA as the plane, and my intended destination were Minneapolis. GA's response was that this gate was never Milwakuee but Minneapolis. My earliy morning response "Whatever, the cold place I need to go" GA then confirmed it was my flight but I had lost my seat, it was ORD-MSP so I was airborne 90 minutes later.
