Unf***ing believable!! I am going through similar experience. I had a burger at A&W and part way through I started to smell a rotten meat odor!!! Well I chucked the burger even though burger taste okay..but this is 3 f***ing days ago and I can barely bring myself to eat any kind of meat!¡ I even smell it walking down street and ask my buddy if he can smell it... and he thinks I am nuts!! I will never ever enter an A&W again in this lifetime!!! Lemme know if you get rid of it and how you did it. I am using vodka!!! I can't smell it anymore for couple hours but I an trying to kill it!!!!!! And it is....who the f*** knows... sorry for language...but at end of my tither.
