Attorney took my lunch out of the microwave in the middle of cooking while I was standing there

I can’t believe how disrespectful what just happened happened was. I was microwaving my lunch and an attorney strolls in, sees the microwave is in use, and impatiently taps his foot. He walks out and back in a couple minutes later and I hear him say „oh come on…” under his breath, clearly upset that my potato is still cooking.

He then opens the microwave, takes my lunch out and says „I’m just gonna…” and then puts in his Tupperware and zaps it for a minute.

I said „seriously?” He said he has a deposition and is in the middle of questioning.

I don’t care WHAT your excuse is, first come first serve. And do NOT touch anyone else’s food. I had to throw out the potato and cook another from my break room stash.
