Needs more choices on soda pop menu

I was just wondering why restaurants don't have diet 7UP or diet Sprite or even diet root beer? They are all not only diet but also caffeine free. There are so many people that can't have sugar or caffeine. We eat out often and the restaurants don't have these pops. My husband brings his own pop. We do think they could carry one of these pops.
