With my mob you have to be on your best behavior. There is a dress code (mostly what not to wear) and you don't tell folks you're staff.
One of my staff had a guest on a guest pass, when we had those, and he created a bit of a scene in HNL with the gate staff. Apparently didn't like being treated like all the rest of the stand-by pax. That came to me as a complaint for investigation. I held a hearing. Guest was banned from further guest pass travel and staff member and family (for other reasons related to the guest pass) were suspended from staff travel for one year.
I've also written up a CSD for rudeness and arrogant behaviour when I had the audacity to question why the Fasten Seat Belt sign was on for 6 hours of a nine hour flight during one of the smoothest flights I've ever had. (He had conspired to do this to keep the pax out of aisles - not just during the meal service). Slimy little bastard was hauled up in front of his management.
