A public pronoun is nearly the same as a personal pronoun only better used for public and social settings. Where they/them can be someone's personal pronouns it is more proper to publically and socially engage with said person with the more triditional he/him she/her Mr/Mrs Sir/Ma'am which are public pronouns.
Hello Sir and Ma'am welcome to my Bakery may I offer your some samples, perhaps a nice mini strawberry cupcake for the little miss? Oh and we use public pronouns here at Sanity Bakery.
