<human>: Provide a brief overview of the text.

I paid for college delivering and making pizza for a company that rhymes with Schlomino's.  One day, after a crappy night of tips, I got a delivery to a dorm on the edge of the delivery area.

I got there, and had to wait while the customer ran down 8 flights of stairs because the elevator was broken.  He handed me a check, written for exact change.  Something like $6.43.

I looked at the pre-written check, looked up at him, and told him I needed ID, which of course, I knew he hadn't brought.  

He turned and went back to his room.  I gave the pizza to the RA, and mentioned that if the guy had tipped the pizza guy, he wouldn't have had to run all the way back up to his room for ID that I didn't even bother checking.
<bot>: Make me wait while you run down 8 flights of stairs because the elevator is broken, then don't tip the pizza guy?  You are going to be making a second trip up and down those stairs bro.
