These nonmembers are beyond shame. There are others that don't care if they are called out as long as they get what they want. But the vast majority don't want to be seen as a loser and by posting their names, it might just stop some of these guys. Sending them an email when they initially pick up the trip will take away the "I didn't know it was disputed" story.

I don't have a better idea. But when I fly with these toads they get to spend the trip eating by themselves, as I consider them in the same class as a nonmember or scab...
