Frustrating night at the movies

What a horrible and frustrating experience we had last night.We went to go watch Avengers End Game last night. It took us almost 45 minutes to get our popcorn and coke as there was only 4 tellers operating (which almost made us miss the begining of the movie) then we finally got to the front to be served, we were told that they had run out of popcorn by 4pm that afternoon. That is absolutely shocking! How did you not cater for all masses knowing that it was opening night of a well intisipated movie and it was a Friday night??????? And how can you only have 4 serving counters open????
