No, you're thinking of the service being faulty. If the lolipop is broken when you open it, the store owner should replace it. If the lolipop is fine, but you're having an issue unwrapping (using) it, that's not the store owner's job to help you with. If he helps you with it anyway, that's him doing something you didn't pay him to do.
If the service itself has an issue, the proper response is what they always do: reimburse you for time lost.
If you have an issue, Lub / Ephi have no obligation to help you.
