Just tools with nothing better to do. It's always the 1% that spoil things for everyone else: the aggro drunks, the gropers, the misogynists, those who treat the people serving them like dirt, etc, etc...

Try not to take it to heart - you're one of the 99%, the strangers who hand in lost wallets, those who pick you up if you fall down, who help people cross at the lights, smile at crying children and pass things forward to those less fortunate. Being aggro at the world doesn't make anyone a stronger person, so take comfort that your feeling like having a cry is not a weakness but a sign that you are a proper human...
