In fact, in nearly 30 years of working in the service industry (as well as in my personal life) I can only recall two occasions when I broke that rule, and in both those instances it was only because each of those individuals asked me to. I also feel its now my turn to get the respect I always gave to my elders growing up -- and still do.Its never inappropriate to address someone formally, and as I pointed out above many establishments require it. In interacting with nearly a million people over the years, no one (regardless of age or gender) has ever complained about me being too formal. However, doing the reverse could most certainly get you in a lot of trouble.
