This reminds me of many years ago when I was backpacking around Australia. For whatever reason, I was wandering around a smallish town around 10am on a Sunday morning and ordered food from either McDonalds or Hungry Jacks (aka Burger King). I was the only customer, and after a few minutes, she called me over and gave me my money back. I asked why, assuming that they'd just discovered they'd run out of ingredients, but no, she said it was because it had taken too long to prepare, so it was free. This is something I'd never experienced in the UK before, and in fact McDonalds in the UK can sometimes take 10 minutes - compared to back home, it hadn't struck me as being particularly slow. It occurred to me that I was probably their first customer of the day and that anyone else who rocked up on a Sunday morning on other weeks as their first customer would probably also get their food for free as e.g. fries would be cooked on demand instead of being ready.
