Pizza Hut

I ordered a few pizzas for my coworkers on 10-2-2019 around 8pm and the guy that came to deliver them was extremely rude. I don't usually leave a tip for this location because the staff is usually really rude and as this guy was leaving he said real loud "thanks, you're a big tipper!" This is exactly why I don't leave a tip. This guy is very unprofessional and inappropriate.
He didn't give me his name but the number he called from was 319-939-1245. Not sure if this is a personal phone number or the company phone.
