Burgess paid for digital conversion out of his own pocket two years ago by raising prices and barring patrons from bringing their own food and beverages. While the policies riled some customers, he saw it as necessary to stay in business.

I must confess, I always did like those concession stand ads with the dancing popcorn, sodas, and candy.

While the digital conversion did not increase attendance, Highway 18 remains profitable, Burgess said. Many drive-ins are not, because owners aren’t willing to take a hard-nosed business approach, he said.

‘‘It’s a terrible business financially,’’ he said. ‘‘None of the major cinema companies, like AMC, own drive-in theaters. There’s a reason for that. They don’t make money.’’
