I think a note is a good idea.
And I have sinus issues too! And I'm a mouth breather as well so I do understand about that tickle in your throat in cool/cold days.
Just today, I had to stop by the store and I was going to rush in and out so I was in a hurry. Once I got to the check-out counter, I stopped to catch my breath. I could feel the dryness in my throat so I started to cough. Since I also have allergies, you could hear a
tiny bit of congestion.
I swear, everyone moved about a mile away from me!

(and of course, I do cough into my elbow or into my top so it wasn't loud but boy...people were scared!)
It was kinda good because I need to stay healthy for my son so if people want to move away from me, all the better!!!!!!!!
