Hello all, 

Posting this on an alt account for obvious reasons.

I work as a research chemist in a large research center. As you can maybe guess, people here aren't always the best with social cues, hygiene, etc

One of the older chemists that works with me on my floor seems to frequently make trips to the bathroom. From conversations with him, I know he is originally from a foreign country (this will be important later, maybe). Now the frequent bathroom trips aren't an issue (who cares), but it's his behavior in the bathroom that I take issue with.

He will spend upwards of 15 minutes grooming himself in the bathroom. This includes, but is not limited to: brushing his teeth, shaving, washing his face, etc. He tends to make a mess and take up space when doing this, but what really grosses me out is the sounds he makes when doing this. All manner of slurping and gargling noises as well as gutteral throat clears and spitting of loogies. It's a show. He also does this whole act regardless of whether there are others using the bathroom or not. I mention the fact that he is from another country because I believe cultural norms could be at play here, as well.

So my question is two-fold. 

1. AITA for thinking this is disgusting and should not be happening?

2. WIBTA if I mentioned something to him?

Thanks
