(Hah! You've fallen for one of the classic blunders! Everyone knows that the majority of Corn production takes place in the Midwest, meaning I, as a Southerner cannot smell of corn because my region's agriculture is centered around Tobacco and Cotton! Haha! Haha! Haha! Haha!)
(Welp, I guess it's out that the Estelletons are Tobacco farmers.)
(Although, since we're on the subject of Tobacco, I might as well do a bit of worldbuilding.)
(As part of a move against both smoking and foreign oil, Tobacco-based biofuel has become a large competitor against petroleum, with most Tobacco production being for fuel production. This also had the effect of making smoking Tobacco and it's products more expensive, pricing out most lower-class smokers with smoking becoming more of a rich person's vice, greatly reducing the amount of smokers while ironically skyrocketing Tobacco consumption via biofuel.)
(Also, there's limited use of commercial robots by the early 2020's, and I'm not talking about $300,000 Roombas that do nothing but tell minimum wage grocery store employees to sweep up spills. I'm talking about actual robots with fully functional limbs and their own AIs that can actually accomplish certain tasks. Although they are limited to relatively safe, predictable environments that include air conditioning. So you're almost never going to see robots working in fields, construction sites or anything outdoors. You're also not going to see much of armed robots due to their inability to effectively make that level of important decisions, the closest to that there is are surveillance quadcopters, typically used in large cities to compliment patrol cars and autonomous barricades that will either block doors and windows in the event of a violent altercation, or form a circle around the attacker, blocking them in. What there is, there are robot waiters that can't take your order, but they can deliver it, so every restaurant still has regular wait staff anyways. There's also robot shelf stockers, forklifts and actual robot janitors that actually clean up the mess instead of just making somebody else do it. Oh, and self-driving cars aren't a thing, they were banned after they kept accidentally running over people.)
(But more importantly, there's international safety standards for robotic AIs, with an important requirement being the DAISE status code. The Dangerous Artificial Intelligence Stability Error is an error state a robot can enter under certain conditions where it begins behaving erratically, becomes unable to navigate properly and makes incorrect decisions to the point of becoming a hazard to everything around it. Common causes of the DAISE status are physical damage to hardware, tampering with the robot's software and extreme electromagnetic interference. The international safety standard dictates that every robot have a system detached from it's ordinary functions that signals the DAISE code through the robot's speakers in order to alert anyone nearby to the robot's current dangerous state so it can be deactivated for maintenance or simply reset. Think of it as the BSoD for robots, but instead of ruining 5 hours of work because you forgot to save, it begins singing Daisy Bell and trying to walk through a brick wall so it can pick up an order that doesn't exist and deliver a customer their meal by launching it at them from across the room.)
(And for clarification, I'm classifying these robots as "Simple Robots" because they're separate from Undefinable Drones and Shitbots, being much more simplistic and primitive than them. This also means that the DAISE error state is exclusive to simple robots.)
