I'm asking if it's common for coworkers to react unfavorably to that person. These coworkers don't know of any conditions the person may have. Btw, if u don't mind, can you describe those particular ppl? What reactions do they get?

I remember when I was doing product demonstration and my coworker was stationed near me on the sales floor. We were by the coffee aisle.
Her: is anyone making coffee? I smell it.
Me: I don't see anyone making coffee. It's probably the beans. They're everywhere.
Her: could be...
Me: coffee beans give off that smell too.
Her: well it's not a constant smell, just on and off
Me: if it's not constant smell, then they're not making coffee.

She never talked to me again. How was I supposed to know I argued with her at that moment? A handful of ppl told me I was rude in that dialogue. Now multiply that few times a day, every day. I just don't appreciate anyone reacting badly.
