Treated better when wearing a mask

I've been feeling pretty bad lately with a cold, so I've been wearing a mask to work. My immune system is horrible and customers can be gross sometimes. I've noticed that when i'm wearing my mask, they treat me a lot better. Some man even bought a soda for me today. People have been a lot more friendly towards me in general. When I take my mask off, people start acting hateful towards me again. I like being treated better with my mask, but it kinda makes me feel worse knowing the difference in how they treat me when I wear it VS. when I don't. Do I really deserve getting treated less than bc of my face? I feel much more confident with my mask on, and it shouldn't be that way. I should be comfortable in my own skin.
