Last summer a flight I was on returning to ATL had to go around. Evidently the plane that had landed ahead of us was taking too long to vacate the runway. (The airport was busy having been closed due to weather earlier.) I would
guess we were around 10-20 seconds from the runway threshold.

Nobody else on the flight seemed concerned. The aircraft movements were all very smooth. Seemed almost routine. The captain, though, when he came on to explain the go-around, indeed sounded quite perturbed! (Blamed ATC
