KFC review: smell (sewer gas)

On jan 4 2020 at 6:56 pm my family and went to location for dinner and the smell of this kfc smelled of either sewer gas or propane we did stay there to eat intill my eyes started o burn and my nose started to run it was like I was back in basic training going thru the tear gas chamber, I am also a emt for evans mills ambulance services and 5 weeks ago my partner and I went to this kfc and the smell was there I asked the manger what the smell was he did not know and said he contacted someone about it, that was 5 weeks ago also one of the workers was also complaining of headaches, the last visit which was on jan 4 2020 the smell was still there and even stronger then ever I again ask the worker what was the smell and again said it was reported and at this time I think it could be a health issue, and I will be back this week and see if this issue is taken care of. Not to threaten but I will go to the board of health and enter a complaint.
