Pet peeve is when off-duty nonrevs try to cut to the front of the line in plain clothes dragging the spouse, buddy pass riders and 4 kids en route to Disney along with them. If you are gonna do that, make it a little discreet, but some employees just enjoy flaunting it. I remember one b*tch at ATL threatening a passenger who questioned her right to send her kids to the front of the line with arrest for "interfering with a flight crew" if he didn't allow her.
