.Shining Armor wasn't super happy that I was dating both his sister and his wife. I mean, I consider it's understandable that he'd get a little jealous, but there's no need to be greedy. Share the love, as a certain hugger of trees would say..
So anyway I told him maybe he should look into some new hobbies. So he opened a hot dog stand in the Chrystal empire. It didn't do so hot, you know, ponies not liking meat and all that. But he learned from it and he opened a kimchi stand a few months later. That went over a lot better with the chrystal ponies who needed some spice in their culinary life.
Soon, he hired somepony to run that stand for him and split the profits and he bought another stand and turned it into a pancake stand. That really was popular! I mean, who doesn't like pancakes? 
Not anypony. We all love pancakes!
Then he opened other food stands and carts and stalls. Like ones for tacos and bananas and pickles and fries and so on. And eventually twenty percent of all restaurant sales were going through him but then the crystal ponies started getting fat and unhealthy since fast food is bad for you so eat at home kids.
