Crazy how people seem to feel entitled like that. "Seeking permission" to approach someone, disturb their time with friends and their lunch/good time. Just because he's an actor doesn't mean he's no human being who wants to have some time to himself. Not to mention that he has anxiety issues. Imagine how he must feel in a situation like this.
You felt sad and disappointed because he didn't leave his friends behind for people who were sitting in the same bar, permanently staring at him and his friends like some creeps?
In Germany, we have a saying for situations like that:
Er mag zwar ein Schauspieler sein, doch er kocht auch nur mit Wasser.
It basically means "he might be an actor, but he cooks with water, too."
He just wants to have some peace, too.
He's a normal human being, too.
Leave that poor man alone and let him enjoy his time. Imagine the way he might have felt knowing there are people that constantly stare at him and his friends with expectations, making his skin crawl and making him feel uneasy.
Then imagine how he must have felt when these people left, looking sad because of him.
That poor man did nothing wrong, yet he might have felt guilty for the rest of the day or his stay at the bar.
Fuck people like the one that made this post, ranting over their own shitty ways.
