Ick, Cindy ...
Dripping Depends while you eat? I think not and it's an unfair characterization of people who have to wear sanitary items.
Most active people who have bladder problems take a med such as Detrol for control and back up the meds with an absorbent product.
My mom is 88 and has the usual geriatric issues with bladder control. For the most part, it's just leakage when she laughs or coughs. She is certainly competent to know when it's time to go to the bathroom.
The idea that a senior would just "let go" in a restaurant or anywhere else is, with all respect, an ignorant conception. Ignorance is not a crime, it just means you don't know the whole deal.
I hope this clears up some of your misconceptions.
