Dana,
What does it matter if he wants colored polish or not? Are you saying the nail techs budget less time for male manicures/pedicures because they don't have to take the additional time to paint the nails? Therefore, what is the difference from the perspective of the nail tech? If the answer is that the "nail tech needs to allow more time to paint the nails that would not normally be assumed, then your answer makes perfect sense. Otherwise there is no reason to mention the colored nail polish if it is not going to be more effort for the nail technician? Does that make sense?
