In a skillet, cook the bacon over medium heat until crisp, 5 to 7 minutes. Remove the bacon to drain on paper towels. Add the shrimp to the bacon fat and cook until just barely seared, about 4 minutes. Remove to a separate plate. Melt the butter in the skillet over medium heat and add the oil. Stir in the onion and garlic. Cook until starting to soften, 2 to 3 minutes, then add the okra to the skillet and cook for 5 minutes. Stir in the lemon juice (this will help cut the slime). Stir in the rice and saute until the onion is lightly browned, about 3 minutes more. Add chicken stock, salt and pepper and bring to a boil over high heat, stirring to loosen any browned bits in the bottom of the skillet. Reduce the heat to low and add the shrimp back to the skillet. Cover and cook until the rice is tender and cooked through, about 20 minutes. During the last 5 minutes of cooking time, use a fork to stir the bacon into the rice. Fluff and serve.
