After I 'quit' Friendly's I started working at Carrabbas that was a much better experience, it was still full of drugs and shit, but the level of human-trash was elevated, and the people really cared about the food and I honestly thought it was amazing after seeing Friendly's and expecting all restaurants to be run the same.
Carrabba's was really good and the people really cared. It restored my faith in humanity.
But they wouldn't give me enough time off for tennis practice and matches so I left Carrabba's after a little less than a year, good times though.
Later in college I worked at a local pizza place as a delivery driver, and the things you mention above make the pizza place i worked at sound like a 5 star Michelin, I have so many un-godly stories from that place but suffice to say everyone was drunk delivering pizzas that was just entry into the club, the owners were heavy alcoholics, real alcoholics, they had delirium tremors etc, etc.
when i have time i should return and recount some stories they are WILD, hard to believe honestly.
