Went in to see a movie and the lights turned on in...

Went in to see a movie and the lights turned on in the theatre about 5 or 6 times while the movie was playing and was pretty distracting. Manager gave us coupons for the next time we come in so that makes up for it but still kinda sucks that we got blinded by the lights so much when we were just trying to watch the movie. Owners need to fix the problem and management told us that this is a problem they have every day so why isn't this fixed?
