I read somewhere that the "scent infusers" had some sort of accident where the "popcorn scent" had been burned onto something in the infusion system and that it was taking time to burn off the intense smell.
The reason for the burnt popcorn is become of an accident when making the popcorn smell. Whoever was doing it, spilt some of the as to make it run on the machine. So the machine is sending out burnt smells insted of nice popcorn smells.
Thanks everyone for the answers! You know as we were walking between the two parks
one afternoon, I thought what is that wierd smell, then I remembered reading on these boards
about the popcorn smell. It just was a different kind of a smell!!
