movie

I was shocked to hear that one of my friends have never gone to restaurants before he came to London. He said he has seen people go to restaurants on movie and he knows
how he should behaves. I guess he was so nervous when he went to restaurant with his
friends.
Do you have something you have never done but you have seen on movie and lean how to
do for?
I was thinking today that if I have something which I have never done but I have seen on the movies.
