Three guys sitting on a bench

So a new office worker just joined and was sitting outside for lunch and sees two guys opposite sides of the bench so he sits in the middle eating his food. The guy on the left says,” Well.” The guy on the right says,” Yeah.” The guy in the middle sits there and says,” Well Yeah.” And then later leaves. The guy on the left asks,” What do you think of the new guy?” The guy on the right says,” He’s fine but he talks a lot.”
