I personally dont think It was a bad decision of the anime at ALL. Especially If zoro dosent know It was him.
Zoro is shown to have possible coc since sabaody in the anime. And even in wano when he intimidate that sumo Dude that wanted Kiko as wife.
And here he shows again in the first part of the party intimidating a Guy and actually used It for the FIRST time after the guards make Fun of the people of kobore town , and zoro had a great interaction whit those people and Yasuie.
