Pizza delivery bros put up with a lot of shit outside their job descriptions. I'll take a non-evidence backed gander here and guess at least half their runs involve tending to the insatiable, booze-inspired appetites of drunken fiends eager to soak up that last round of shots that sent them rolling onwards, steady into blackout station. If these greasy factoids carry anything remotely close to the truth in 'em, then hell, I'm inspired to tip extra the next time I call upon their heavenly services.
There's nothing worse when you're working in the service industry than having to deal with someone like this. The kind of person that has disrespect and disregard for other people and their emotions as they go through the day carrying tirades of abuse and crusades against all who dare to stand in their way.
This brave soul reached his limit with his girlfriend after she was disrespectful and rude to the entire waitstaff when they went out for Valentine's Day dinner. This abominable human being got what she deserved.
