Same thing happened to me, and this was a weird-looking one who had a free hand while  yapping on the cellphone. They just want and crave something to moan about. Gosh if you hold the door, even if you don't. moan if you say hi, moan if you ignore them. complain about the way you sit (complaining?!), while their backside takes two seats. Stupid! Stupid! Then moan some more. I just flipped the birdie, and kept on walking.
