There was the mid-credits scene with Thanos and The Infinity Gauntlet (Avengers: Infinity War! WOO!), but no silly, post-credits, shawarma-esque, end scene after ‘Avengers: Age of Ultron.’

I personally think they should have had Steve and Tony testing Thor’s hammer in an elevator. 

Steve Rogers: But if you put the hammer in an elevator? 
Tony Stark: It’ll still go up. 
Steve Rogers: The elevator is not worthy.
