Im just thinking out loud but….
how is going to a store with the sole intention of shopping, when one knows for sure there will be pritzus around, any different than going to the beach ? There are other stores that dont have pritzus around, and there is always the possibility of ordering online from that specific store (to get around the issue of nidda in the water, assume they arent going swimming but want to enjoy the boardwalk during the day/ volleyball)
