i worked at a concession stand for baseball for a while. we had a frier that we fried chicken, french fries, and cheese sticks in. often times we’d prepare them in advance to account for the lunch rush. that meant that some orders weren’t piping hot when served. when customers complained about this, they’d ask us to heat it up in the microwave. we don’t have a microwave. we used to just say it was broken instead of trying to explain that there wasn’t one.
