Nowt unusual.
Plenty of prossies give a postcode of a local landmark, pub,
restaurant, post office so that punters can plan there travel without the prossie giving
away too many personal location details. The proper address will usually come in the
comms immediately pre-punt.
No worries she gave a school postcode. There are plenty of houses and apartments
opposite and all along the rest of that road.
Also if you plan your punt at school opening/closing time you might be able to eye up a
few yummy mummy's or hot teachers that get your juices flowing in time to meet up with
said prossie.
