i don't see any problems if they clapped.

you are not in a classroom, library or boardroom.

it is a movie house. they were just enjoying the movie. for as long as it is not harmful and disturbing the flow of the movie. let them be.

i believe that there is a VIP section at city centre wherein you pay QR 100 for a movie.

for sure there wont be no clapping inside because not everybody wanted to spend QR100 in a single film.

try to relax when you're inside a movie house. focus on the story line and in your popcorn. not on the clapping.

There are so many rules to follow in this part of the world and adding restrictions to the clapping inside a movie house is not a good idea.

Chill!
