ugh.......this is the kind of behavior bred from the tipping system
from an article I read about a chili's customer finding spit in his soda after sipping from it
“I saw the spit in the cup,” he told the paper. “It wasn’t regular spit either. It was definitely a loogie.”
they took it to the police who got a cotton swab from the waiter's mouth and dna test proved it was his loogie. then he admitted to it and got fined, lol
