I just ordered pizza. It was $24.89. Guy got here faster than I expected while I was washing a few dishes. I told my friend there is $30 on the table, give him all of it. I heard him say "just $5 back, you can keep the change." I asked him wtf, and with the pizza guy still digging for a $5 my friend said "F*ck this guy. He gets a paycheck." That got me wondering if people like him know they are not going to tip before they even pick up the phone. Btw I told the pizza guy to keep it.
