Having a customer service page is not synonymous with being accountable. The thing is, whether or not we are satisfied with them, we still have to deal with them until the government changes it. So they aren't held directly accountable. Instead, we have to effect change in the government in a way that will then effect change in the TSA. That extra layer makes things much harder.
You know, i totally agree...i just ask myself "would it hurt if they were friendly" and i don't see why not. They are citizen facing, treat others as you would like to be treated. It just feels like common sense to me.
