I went into a public bathroom today and there was a guy who was rinsing his mouth out with water. He did it a couple of times in a row, and naturally, my instant reaction was to think he just threw up and was rinsing out is mouth.

Now I can't stop thinking if I was exposed to something

I washed my hands for a long time but didn't use a paper towel to turn off the water or open the door because I had just seen him touch the paper towel lever....

What do you guys think? I didn't smell any vomit, but I just have no idea if there were vomit particles floating around that he may have caused...
