Pizza Delivery guy problems

What about, "that'll be $24.88"... "Here's $25, keep the change!" : ) My wife did this job in college

When I worked at Dominos we always told them over the phone that we can't break a $100, then they'd be mad when they asked when we got there. "Now I have to go to the store to get change! Can you follow me up there!?" *No tip*
