Burger King Ottery Stink Restroom

I went for lunch with my friend at Burger King Ottery. Before we left the restaurant I urgently needed to use the restroom as I was far from home. My order number was 1114. There was a very disgusting foul dead rotten smell in the restroom and it made me sick sick sick. The restroom looked clean but it was very unsanitary. It smelled like the sanitary bins have not been emptied in weeks. I did not even sit down on the toilet. For a restaurant that sells bottomless sodas.. Its embarrassing for a restroom to have a bad smell.. I went to the manager on duty and i explained to the manager the awful smell that was in the restroom. I told him for the fact that I just ate.. It made me so sick.. I explained that the it smells like the sanitary bins have not been cleaned in weeks or something.. While still speaking to the manager. One of the staff members came up to him and he told her to go empty all the bins and wash it out because the customer is complaining. Wait.. Is there not a special kind of cleaning company that you call to clean out your sanitary bins.. Or am I wrong. Anyway... The manager then continued to speak to the staff member on hand as the staff member explained of some type of spray they used because they did clean the toilet and it was the mop. But i swear to God it was not a mop smell. I then walked away and i left the restaurant.. Not even long outside and my entire meal that I had came out again because of this awful smell. I feel that it was unhealthy.. Unsanitary.. Disgusting.. Disrespectful.. I mean the restaurant serves bottomless drinks. I would never go there. Wasted a my money on Burger King Ottery only because they can not keep their restroom clean🤢
