i got the best ending for the fair event but i have yet to get to repeat it too so i think its just that event is a one time thing. and also there is no way to tell if you got the event if you already got it so if you cant get it maybe try the other steps? the yell at barrel event shows up anytime so if you do every other part if you dont get the scene with him in the house then that would mean the bar should be the last thing.
