Imagine you had just ordered your lunch at a takeaway joint.
As you wait, you watch the team busily preparing orders, and you can see your food being made.
You notice the worker sneeze over your food. Not an awful one, but enough to spray directly into your lunch. They dutifully wrap up your food, pass it to the counter staff, who call out your number to collect your lunch.
What is a reasonable response to this scenario?
Hypothetically you'd just use your rewind laser to rewind back time to before the sneeze and then call out to them to turn their head away from your lunch.
