I normally don't have any issues with NRSAs (I feel they earn the flight benefits they get), but I just have to report this event from last Wednesday at SFO.

We're sitting at the gate waiting for UA 837 SFO-NRT, when this guy approaches another passenger and asks to "rent" his shoes for the flight. Apparently he's a NRSA (from UX we learned) sitting in Business Class, and didn't have the right shoes to match the dress code. After five minutes of cajoling, the passenger eventually refused and the employee went away. Then, two minutes later, he approached another passenger with the same scheme. At this point, someone reported him to the gate agent, who downgraded him back to Coach.

Isn't there a code of conduct for NRSAs? Shouldn't he have known better to (a) have the right shoes in the first place, or (b) not bother paying passengers because of his oversight of (a).
