I'm 66, single female, love to go to movies

BUT how many of you can find things to eat that are o.k. at movies--other than maybe a diet coke or sometimes tea??

I live in Tucson, AZ, where there are several multi-theater complexes. I go at least once a week (after work as elementary school librarian).
When low-carb diets were the THING, I went to movie complex managers and begged for snacks for people like me. Most got in the low-carb/no-carb ice creams--for a while. But now--nothing!! And try to bring in your own foods
We diabetics need to form a national group to interact with movie theater chains and get foods for us put in--nuts, seeds, no-caffeine drinks, sugarfree candy made with Splenda--NOT maltitol/etc which cause bad reactions in so many. Anyone know how to do this or of such a group!!! Would you join?
NOW'S THE TIME!!!
