A little late, but maybe someone will see this. I was mystified, too. I Googled around a bit, and found several articles mentioning, since at least 2007, a fad of throwing drinks at fast food workers while yelling “fire in the hole.” They said there were YouTubes of this obnoxious practice (which I didn’t look at). One article showed a worker who was burned when some jerk threw hot spinach in his face. >:-<
