just ask them to
"cover up for safety, cover up.
put my mind at ease,
wear your covers, please.
cover up for safety, cover up."
(sung to tune of "buckle up for safety"

btw, as much as you might think, there is no simple this extreme versus that extreme in this sub-culture. there are just too many variable factors involved, resulting in a wide spectrum ranging from low to high, with many points in between.
so, i look for a woman who is attractive in my book, has a consulting fee i can afford, is with easy driving distance [maybe i should use DART handirides], and has a good reputation for service with a smile [based on either reviews or first hand experience reports].
