Your customers didn't do anything to deserve your entitled disrespect. nor will taking out your personal frustration on them do ANYTHING to "prove" what a big and important person you are to your management.
That's like doing a double-fisted Uzi drive-by on your target standing in a crowded room, when what you need is a sniper.
Put your backpack back on, vote no, have a beer, and let the personal side of it go. Your customers are not your enemy.
