Oh yes, but this last year I've been trying really hard to break the habit. But yeah, once I get into a food routine it can become extremely detailed and repetivtive. Generally it's one to two meals of the day(lunch/breakfast/dinner), and I have the exact same meal every day, have to make it in the same pattern, and have to use the exact same quantity of each ingredient.
Eg. I was having tuna salad for lunch for a while, and I would have a 3rd of a carrot chopped in a specific technique into thin strips, a quarter of a green capsicum chopped into thin strips using a different technique, one green chilli diced into thin circles then with each circle cut in half, half fresh cos lettuce and half parsley both scrunched tight in my hand and "diced" from one end as I slowly move my hand towards the other end as a green base, both have to be bought from a specific fruit and veges shop, Thinly sliced red salad onion with each "circle" then cut in half, black pepper ground on top of the ingredients, then a large piece of white goats fetta crumbled on top, one small can of John West lemon and cracked pepper tuna, drained in the sink, then tipped on top, half a lemon squeezed on top of that, and then about a tablespoon and a half of olive oil poured on top of that. Then I would use the fork I used to extract the goats feta from its container to stir everything together inside my bowl until it was fully mixed.
I get upset/stressed out if I can't have the right ingredients (which have to be sourced from the right place and be the same brands that I always buy). Other snacks which I have repetitively are SPC salt reduced baked beans and Mainland Colby cheese melted together (half cheese, half beans) in one of my small china bowls, heated and melted in the microwave, taking it in and out and stirring, until the cheese is just completely melted through, and then eaten with a teaspoon. I always use a teaspoon to eat every "spoon requiring" dish (eg. yoghurt, baked beans, dessert, etc) except for soup, which I use a soup spoon to eat. I can get very rigid with my habits.
