From what I've read lately, many truck stops still have hot food available. Some make it to order instead of having it available under heat lamps. I'll have a better idea after returning to work next week. Wisconsin has also mandated no self serve hot beverage dispensers to be used. Staff will make your beverage while wearing gloves, then hand it to you. Some locations are limiting hours when coffee is available. Some restaurants have become rather creative in serving their customers.
