Curses, Foiled Again

I thought I read somewhere that aluminum foil is supposed to be wrapped shiny side in because of the coating on that side of it (to avoid interaction / reactions with the food). Food service establishments always seem to wrap their foods with tin foil, leaving the shiny side out. Here I am, wondering how it is they wouldn't know that!

Well, I was wrong. (It's rare, but it happens.) The food packaging guide corrected me, as did Reynolds (the aluminum foil company). But even so, shouldn't the shiny side reflect heat better? Perhaps the shiny side might stick less to the food (because it's microscopically smoother)?

One thing I know about tinfoil -- the rolls aren't wide enough to make nice foil hats with, before you go venturing into a crop circle.
