I’m sorry you’re eating downvotes but this is the absolute truth in a lot of cases. I put in 18 years at various restaurants, worked every position except manager. I’ve never needed a drug test to get a job, and every job I ever had in that industry people were definitely on drugs at work, but drug tests are mandatory after a workplace injury. The reason being they don’t actually care whether you’re high at work but they can use the fact that almost everyone in a restaurant is high in order to cut costs under the guise of “workplace safety”.
