Dude, I don't know who needs to hear this, but if you order $300 worth of DELIVERY food and live on the third fucking floor of an apartment building with NO elevator, and your driver/delivery person has to make three fucking trips to your apartment, FIVE FUCKING DOLLARS IS NOT ENOUGH OF A GODDAMNED TIP!
10% ISN'T ENOUGH EITHER. You've just ruined that person's day, AND you are a cheap fucking bastard. FUCK YOU.
