Which one is correct?
1: Well, you canceled on Tuesday and our policy is 24 hours' notice for all cancellations.
2: Well, you canceled on Tuesday and our policy is 24 hours notice for all cancellations.
To me personally, the first one makes more sense grammatically. But I've also heard that the second version is how they typically write it on paper forms at hospitals (that's what native speakers say). Could you please clarify my confusion?
