Depends on passenger type quite a bit in my experience. On vacation flights it is pretty common, especially if many elderly who do not have much experience are on board. On a flight with an all suit-package in the cabin? It is just a disgruntled "finally" and receiving their emails/texts from the passengers.
But all in all if something out of the ordinary happens like extremely bad weather, go-arounds or both combined passengers are more prone to applaud and thank the crew on deboarding, even more so if there was a real issue and everything was fine after a full cabin preparation.
