The Coffee House has had its moments where certain noxious fumes would empty the place for a while. That's why we have exhaust fans now that we crank up on Chili Day.
So, do you come back inside hoping that no one decides to reenact the Blazing Saddles baked beans scene? When you see the coffee pot labled, "Bromine", do you pass it up and have some Sumatra instead?
As Lt. Frank Drebin once said in the first Police Squad movie, "You take a chance just getting up in the morning or sticking your face in a fan." I still think the Coffee House is a good place to relax, have some fun, and hang out from time to time. I'm also not allowed near the fan.
