Prank at a Drive-Thru

I was pulling a prank with someone at a drive-thru. I had to order something with “fire” in the same, but I had to specifically say “be sure to put out the last one”, the joke being I lit the place on fire. I remember I was very hesitant about this and trying to find a way to do it as subtly as possible. Dad was stumbling around at a bar from what I remember.
