Honestly toilets near kitchens as not that strange. Friend rented a home with one behind a door near the backdoor of their kitchen. Because a pipe from ran through there.
Also someone else I know in a 500k+ home has a toilet right by there kitchen where you come in from the garage. Sure there is a hallway. But you can see straight in there if the doors open and if you measured it's probably less than 6ft from his fridge. Guess the illusion of it being less gross is there is some separation?
It's not an illusion. There's enough disgusting stuff on my vegetables, when they come fresh from the supermarket. No need for poop particles in my cooked food.
