On our last trip to Vegas I used the kiosk machine to check in to my flight home and printed out a boarding pass. Instead of getting a plain paper print out, the kiosk seemed to have some sort of fax/thermal paper printer.

There was an issue with my GF's check in and we just waited till the airport to check her in. Got LAS checked my bag and got a stamp by the check in agent on the boarding pass, she checked my passport etc... gave the GF a paper boarding pass and we headed to security.

Hit the TSA line and the agent was convinced and informed me that she was convinced that it was a fake boarding pass. After a few minutes, she shruged and said "whatever" and waved me on to the machine.

Just seemed odd, I've never been told I have a "fake" boarding pass before. Anyone else have this happen to them? If they refuse to accept it, do you just go back to the check-in desk and ask for a reprint?
