This is not acceptable. She can pray in any place. All what she needs a place for her to stand and prostrate. This can be done in the place she is standing, in the warehouse, in an office or in the street outside the shop.

A sister live in USA working in a shop there is no place to pray except bathroom, she wants to know is it ok for her to pray in bathroom ? or pray after she get off the job ( delay Duhr and pray Asr at home together)??
