“Do any frum women clothing stores prohibit men from being customers or coming in for whatever reason?”
How many men walk into (name your frum womens clothing/accesories/nail salon/ store here) in any given week?
Are you somehow implying it is appropriate for a man to walk into say, (I am making this up, any store that has this name, apologies) Friedmans Female Fashions?
How many frum stores play music of ANY kind, let alone non jewish woman vocalists or a radio station. How do you know it wasnt a jingle of some sort? Perhaps the owner didnt come into the store that day and a non jewish worker decided on the selection of music for the day? Why do you believe I think it is OK for a store to play non jewish music, especially with female vocalist, because I am trying to find a reason that another yid didnt do something wrong? Try not to look for and point out every negative thing about another yid. Look for the positive. Especially during the three weeks. If you do that, perhaps if this yid IS playing objectionable music, they will take you seriously if you point it out to them.
