Rowan Atkinson
Famous all over the world for his character Mr. Bean, Rowan Atkinson is quite a character himself. In an encounter with him, a fan recounts that Rowan swore at them when they tried to go up and meet him. This is very odd as his funny character in the famous show makes the masses believe that he would be a delight to be around.
It is a shame that celebrities often turn sour or arrogant when their fans try to meet them or have a nice chat. Humbleness can go a long way with such celebrities and make the masses like them in reel and real life.
