I reviewed this place, and an attempt to a justifiable reason for the rudness of a staff member goes like this in the image posted below. If you don't want individuals bring phones in to potentially put a call through to a spouse, friend before making a purchase then place a signage bold and clear at the entrance stating, " PLEASE PHONES ARE NOT ALLOWED IN STORE, DON'T MAKE CALLS OF LOOKUP PRODUCTS WHILE IN STORE". Make it clear, don't build up policies on the spot and make decisions based on suspicion of your long term clients . Thank you
