Selling Popcorn at Our Internet Cafe

Hubby's customers love to munch when they are using the internet at our shop. Especially the students when they are doing their assignments. We do sell a few types of tidbits but recently we have some requesting for popcorn. I love popcorn too. We are thinking of investing in buying popcorn machines if there are more of them requesting for popcorn. I think the cost of making popcorn is not high but the returns are good. And also I can eat popcorn till I puke! hahaha.
