Reddit user ohyaycanadaeh is a substitute biology teacher—for middle school students. Dealing with hormonal, teenage students can be a particularly arduous job, especially so when teaching a subject that may be difficult for some to grasp. In order to make sure students understand the material, the teacher ends each lesson with a question:”Does that make sense?”

It’s a normal question you probably heard often as a student. But herein lies the problem—the user works nights at a liquor store, a completely different line of work.

If a customer asks ohyaycanadaeh for help, the user reverts back to old habits and automatically responds with a “Does that make sense?” Of course, that sounds condescending-as-hell if someone is just asking you to point them in the direction of the milk aisle.

The user suffers from a problem we can all relate to—bringing our work habits home with us, habits that may come across as bizarre or just plain psychotic outside of the office.

From a substitute teacher moonlighting in a liquor store to dishwashers who are compelled to clean other people’s dishes (best friend ever), Reddit users discuss strange habits they picked up from their jobs. Here’s what they wrote.
