Again I would have to respectfully disagree. You have a base price yes of 5-20$. But don’t forget about the concessions movie goers spend money on. Most of the revenue is concessions.
What “greasy spoons” do you dine at? You ain’t touching any full meal of the day for under $15 not including tip/gratuity. People will always dine out just as people will always go to theaters to watch movies.
