You'll be fine. I worked at a pizza place for ever (lol just felt like it ) and they would leave pizza out in the display case (even ones w/ meat) and at the end of the night before thowing it out my boss would eat a slice cold and was fine, the display case wasn't a heated or refrigerated one so it was room temp and open to all the things floating int he air and I think my boss was probably the healthies guy there and he did that allt he time and never got sick so you will be fine is the point to this loooong post. Also my ex would get pizza, leave it out ALL night and eat it the next day, never got sick. Hope this helps! Enjoy the party today!
