About 7 years ago I was flying an RJ. A middle aged UPS captain asked for a ride up front. We of course granted it. Once out on the taxiway the airport was closed for departing traffic and we were told to shut down. For another 1 hour we were beat to death with his complaining about how it was utterly insane that UPS only paid him $225,000.00 a year base pay. After listening to him for much too long I pointed to my new hire FO and said to him "do you have any idea how much she makes?" He said "no" and I told him "about $18,000 base" His response took the cake when he said "Well why would you work here?" and then went on about how expensive his kids private school was. Some guys just don't have a clue.
