You sound like me when I go down some candle aisles. I hold my nose with one hand and push the cart with the other hand. Don’t get me wrong. I love smells. I found some pine cones that were scented with cinnamon today but it was so strong that I had to pass on them. I have a large glass vase which they would have looked great but my health comes first and I already have an allergy problem.
I can't even go into some of those fancy tourist shops where they sell candles and such. It's not like I'm always on guard for such things, but when me and the family visit those types of places, I get more observant about what kind of shop I'm stepping into after about the third stop.
There are also some types of aerosols the wife uses that can run me right out of the room. Certain cleaning products and so forth can actually shut down my respiration. Weird.
You should quit shopping or going out in public for any reason.
You might detect something that might cause a problem and then the SWAT team will eventually show up and take away the offender(s).
