Buying something you are not allowed to touch or see and not being able to return it if not satisfied with the merchandise

I walk into the store ask to look for a size of their blanket, the manager of the branch told me they are not allowed to open the blankets, i request her and her staff nember to be the ones wearing the gloves, i wont touch it, so that i at least see the physical size she refused, because i am not buying for myself, i asked her since we are not allowed to touch their things why dont they at cleast put it on display, no answer from her.one thing she made clear was their refund policy of no exchanges no refund, but how will i buy something i am not allowed to see and yet not return if not satisfied . What stunned me is, as that as i was busy speaking with her, a gentleman"reffered to as kgothi by the manager" with mr prize uniform inside streetsheet store started going off on me," saying every household has rules and a whole nasty words" i am stunned and amazed by this kind of behavior especially from a young gentleman.
