Years ago trying to catch a UAL flight from NRT to BKK (flight 875). I was a regional F/O at the time in my mid-twenties. The capt. actually pulled out the scab list as I waited in the flightdeck. I thought it was odd since it was obvious (at least to me) I was too young to be a scab as the last strike at any airline was when I was around 15 yrs old!

Oh well, some guys like to show their power.
