So the result is that this 55-year-old, who has a lot of life experiences, has to threaten to break his 30-year-old physician's nose in order to get antibiotics to fix his once-a-year sinus infection.
Works for me.
Uh ... once a year “sinus infection?” And no fever / exudate / tender lymph nodes / other signs of infection, I presume (since your doctor didn’t want to give you antibiotics). With almost no information available, that sounds like an allergy, not a bacterial infection.
More to the point: if it is not a bacterial infection, then antibiotics not only won’t help you, but they will make the problem worse for everyone else, by encouraging drug resistance. That’s not an opinion; that’s the simple fact.
Again, I’m going off just what you posted, but it appears that you may have an allergy rather than a bacterial infection. If so, you should treat it like an allergy, rather than like a bacterial infection. You, and everyone else, will be better off.
