Struggling with Misgendering in Retail

trying to use this app as an outlet again, so hello. recently have been working in retail which has caused me to become a lot more social! i’m pretty productive now a days but unfortunately every time i help customers i always get referred to as “she/her” or “maam”. i like to think i pass, my voice is more mid range in tone, and i dress very masculine..i ignore it as best as i possibly can but over time it gets tiring. you try so hard to be seen as a man out in public and without a doubt it fails.
