And suppose the mikvah lady sees a woman who had a mastectomy or some other disfiguring scar from major surgery, or psoriasis, or just bad acne scars, or maybe just someone who is severely obese? Should she likewise raise her eyebrows, possibly seriously embarrassing the woman, who might then never want to return to a mikvah again?
Lest you think these are idle remarks, I know whereof I speak. I have been zocheh to work in a mikvah for many years, and have seen ALL of the above, and all types of women coming and going. Many are baalos teshuvah, who did foolish things in their youth. Should they be reminded of that every time they go to a mikvah and might have a different person oversee their tevilah each time? Where is the sensitivity training for these “Sheltered” ladies? Before they are allowed to do their job, they should be made to understand thast ANY kind of unexpected visual may come their way in the course of their duties, and they have to learn to refrain from reacting negatively.
That is a sign of maturity and compassion. If one is not capable of showing simple derech eretz “even to the tattoo lady,” perhaps being a mikvah lady is not the best job for that woman.
