HIDDEN CAMERAS IN TOILETS

The restaurant has cameras installed or hidden in toilets... why, I DO NOT KNOW! Myself and a close friend of mine had the worst experience at this place today. We went their to have lunch,He used the toilets not knowing that he was being watched by management. He did what he needed to do and as he came out of the cubicle, three men were standing waiting for him. He was frightened by their presence as he knew he was alone in the toilet and did not even hear them enter. They asked him so many questions,but when 1 of the guys asked him where the object was that he fell out of his hand (it was a gold item) That's when he started getting suspicious cause how on earth did they know that. This incident might seem irrelevant however,I feel that this is wrong on so many levels. THIS IS INVASION OF PRIVACY!!!!! If the men's toilets has cameras then i'm sure the ladies toilets also has them. WHY????? Surely something must be done about this, little kids uses these facilities as well!! #TRAUMATIZED!!!!!
