What's the worst thing you'd like to be stuck doing in a time loop?

I recently had to wait two and a half hours in a doctor's office, just waiting to be seen.

I literally was genuinely thinking "Well, maybe this is a time loop", because nothing seemed to be happening, no progress of any kind seemed to be being made, so I think we've all fallen into those time loops.

It usually involves waiting for someone in a profession where you wait for them; it just takes forever.
