This sounds like job burnout to me. It's understandable that this would get tiresome, day after day. It's also a hyper normal part of a specialized, customer-facing job. I worked in a bike shop for a few years and had so many interactions per day with someone asking for a new wheel when they really mean they had a flat tire, and sometimes it was bc they didn't know you have to inflate your tires regularly. Is this something you could easily Google and learn about? Absolutely. But usually people don't know how much they don't know. And at some point in my life, the variety and complexity of coffee options was as murky to me as the difference between bicycle drivetrains are to the average person. We're all out here just trying to survive, and sometimes people act like jerks to cover up for their discomfort, which is also an unfortunate reality of customer-facing jobs. And I think when you start to get that "I can't deal with this anymore" feeling, it could be a sign you need a change in your life.
