No doubt she did. I'm sure she also has purchased a 2nd vehicle at home in case the first one breaks down, and has a duplicate water heater at home in case of failure in January, and a 2nd ticket to her next event on a completely different airline just in case of labour dispute or mechanical delay. Because these are all reasonable, foreseeably bound-to-happen events, and spending that extra effort and money is totally worth reducing the risk to a lower not-zero level.
