We are pursuing CI for a retail space inside a huge mall. Our employees will use the new toilets we have made for them inside our space, but our customers will use the toilets outside our retail space. If they want, they could use the ones in our shop, but they are not designed to be "public". Could we pursue WEc1, only taking into account our toiletts and NOT the ones from the mall? Once the customer is inside our space and he-she has "needs" they can use our toillets, but it is obvious that they will use the ones from the mall! What should we do?
