It wasn’t a visual scene in a movie, but a story being told. I want to say it was JOe Pesci, but I’m not 100% sure on that, maybe it was in Donnie Brasco. It was definitely a color film, and in English.
So I remember this scene, where a guy is talking about a “hit” he did, where he had to gain the guys trust over weeks and weeks, by spending time at the bar and just being buddies with him. Then one day, they’re walking down the street and the mob guy pulls out his gun and pulls the trigger but it doesn’t shoot, so he jokes with the guy “aren’t you glad you have a friend like me” and they go back to the bar and he goes into the bathroom and works on the gun with a spoon.
