As someone who has done questionable things with propane tanks, and has used some questionable things as jack stands: I think that is as stupid as the average person would think, but for probably very different reasons. Hint: I'm not worried about it exploding. However, I am very worried about its shape and orientation.
Blockbuster? Batteries or vapes or something now. Bowling alley? Urgent care. Movie theater? Paved over. Record store? Gone. Supermarket? Gone like it was never there.
