Yes... you have vending machines selling drinks and snacks ... WHY NOT have vending machines selling cuts of high-quality Miyazaki beef?
For me, I suppose buying something from a vending machine meant you could eat the thing you bought immediately. I suppose this would apply also if you liked raw beef!
Miyazaki beef, btw is very high quality beef. Supposedly the cows are raised drinking beer and listening to classical music.
And of course, if you are selling beef by vending machine ... you will also NEED ...
