Their kiosk UI is unusually poorly designed. It takes more than a dozen clicks to buy what used to be "I'd like a number two with a Coke" at the counter.
Their old number 1/number 2/etc was incredibly efficient and swept through the entire fast food industry.
Has anyone seen a report or analysis or similar on why they abandoned that incredibly fast and effective system and replaced it with a purchase UX (both kiosk and at the counter signage) which looks pretty incompetent to the casual observer.
