Years ago I flew from Oshkosh to Broken Bow, NE, had lunch and then continued on to Ft. Collins. We were picking up the alcohol for my daughter's wedding at a mega liquor store out there. The manager came over and said "American Express would like to speak to you."
ME: Hello?
AX: Are you in possession of your card?
ME: Yes.
AX: Were you at the Hilton Garden Inn in Oshkosh Wisconsin this morning?
ME: That was me.
AX: And were you in Broken Bow, Nebraska at 1 PM today?
ME: That was me, too.
AX: And now you are in Ft. Collins, Colorado?
ME: This is me.
AX: And you're in possession of your card.
ME: Yes, that was me in all those places. Would it help if I let you know I own my own airplane?
AX: Ah, that makes sense. Sorry to have bothered you.
It seems they couldn't figure out how I got between three towns so quickly that don't have air service anywhere near them.
