>The OP above you is guaranteed to have had their food spat in or otherwise tortured as punishment for not tipping.

Wait, what??? Do you honestly believe the worker pours a cup of coffee in a to-go cup, hands it to me, checks the receipt for a tip, then grabs it back to spit in it? What kind of delusional thinking is this? How does the food delivery person even know the tip amount before the receipt? This kind of thinking is exactly why the system is so out of hand.
