Never got why these mangakas love this kind of scene, i don't know why they think everyone must be 100% hostile or have their guard up all the time, people love to talk and gossip, it's not even a secret what they are talking about. In most scenarios like these they would either talk openly with you, dismiss you (Saying things like: "Sorry, we are talking privately.") or brazenly ask for compensation from the get go.
In some of these scenes the guys almost assault the protagonist before them pull out the coin, these mangakas need to get out a bit more...
