If I was John Wick, as soon as I come to know that there will be an open contract for me, I will go somewhere, where normal people live and disappear. Wait for a few days for the wounds to heal. Then have a good haircut and a shave. Get rid of that bloody awful full suit and wear a t-shirt with shorts and slippers. I bet no one will see you as "the john Wick" any longer. Get into a public bus and leave town for good.

Of course it did not happen in the movie because if it is, it won't be a John Wick Movie.

It is a movie full of dull fights and stupid hero.

John Wick 3, producers might have thought that the spectators will be fond of an endless chain of fighting, which becomes very very dull within the first two fights.
