so you got a free pizza, albeit late, and you don't want to give the driver a tip. maybe he got lost the first time, maybe his boss forgot about your pizza and it wasn't delivered cause the order taker screwed up. maybe they wrote down the wrong address the first time and he knocked on your neighbors door, it is totally conceivable that the person on the phone was the one who lied to you not the driver.

I am quite sure your next pizza will have spit in it if the one from last night did not. I have delivered for a living when i was in college, it is not always the drivers fault.
