The episode was alright but the whole pig feeding scenario painted Applejack as, and pardon me for being blunt, stupid. Why did she even need to open the squeaky gate to begin with? All she needs to do is dump the pail into the trough from outside the fence.
I liked that she fixed the problem in the spa and I think it would have been a better premise for the episode. For example, on the way to the spa Applejack ends up getting distracted helping somepony, then she helps somepony else, then somepony else. Then she finally reaches the spa only to help them too, then lo and behold the day is over and there's no time to relax. Turns out, Applejack's Day Off didn't turn out as anticipated. The lesson here is, it's good to help others but working yourself to exhaustion isn't good. It isn't wrong to take a day for yourself and relax.
