If you dread a PPR call, just keep in mind that allowing planes to land and take-off is the sole reason of existence for an airfield - and to a large extent their main source of revenue too. Usually they love to see you come but just want to make sure you've been fully briefed so as not to annoy the neighbors.
It's only in rare cases that permission to land will not be granted, and usually there's a very good reason for that, then. One that makes you glad you called beforehand.
