Here's the longer version, for clarity. This happened in June or so of last summer.

I got the katsudon and was surprised when it came with two cutlets because it usually only has one. It smelled a bit off, but I'm oversensitive so I cut off a tiny piece. It was absolutely rancid, and at the same time my friend across the table was remarking,"I think there's something wrong with your meat." It was so bad other people could notice the smell.

I send it back after telling the waitress that at least one piece of the meat was bad.

A few minutes later the cook comes out yelling about how he just got that meat in and had a tasted and it was fine. Lightbulb goes off in my head! Meat just came in? Two pieces instead of one? I think I was given a leftover from the old supply and a new piece.

I asked if he tasted the portion I had eaten from (which I didn't really expect.) and he refused a straight answer. He told me it was fine, he had a bite, it was perfectly good. It's likely the other piece was fine and the first was just a leftover. I asked this point blank and he got even angrier. He told me he would not make me a new meal because I wouldn't like it either and stormed off.

The waitress didn't even ask me if I wanted anything else and none of us have gone back since.
