I mean yeah but if you clean it, they won't think that. And if you mention you cleaned it, they'd be more inclined to do it in the future.
And, worse case scenario, you spend like 5 minutes occasionally doing it and now have access to a clean microwave, without needing to buy more e-waste and encouraging the production of cheap, stupid things like a water bottle with a heater in it.
When I got this job years ago, this microwave is beyond cleanable... I think everyone is just avoiding it at this point and go across the building to use a different microwave, which is also pretty gross tbh. I thought about cleaning it, but then again I don't wanna, you know, die.
I'm very much a "fix it yourself" kinda person but I might yell at you if you said this to me. Why? Because I'm cleaning up after you. Why don't YOU clean YOUR mess? Maybe it's one person creating most of the mess (Pareto is a bitch), make them do it. Or we pay cleaning staff, pay them more to do it, I'm sure it's less than you're paying me to do it. It's probably cheaper to buy a new microwave every month than pay me to clean it lol
You pass responsibility to someone who isn't responsible. You don't recognize this function repeats and people become over burdened. Sure "It's not a big deal" but that's in isolation. That's one time, one task. These things don't just add up, they compound
