I work as a bell boy for a four star hotel. That means I process walk-ins, check in reservations and carry bags. If I have particularly rude customers, I'll pull out a cane from behind my desk, hobble out and ask if I can carry their bags for them. Then they feel all guilty for being a douche, but I insist and say, "Let me do this, it's all I have left." I then proceed to drop their bags as often as possible and take forever getting to the door. "WHY YES I DO ACCEPT TIPS, THANK YOU"
