Postcode issue!

I arranged for a surveyor to come round today to check if the kitchen floor was damp. Told him to put the postcode in his Sat nav, which he did and it took him to The Jolly Sailor pub and told him he was almost at his destination. Unfortunately, although it is only about 50 metres away, it is on the other side of the river! It is also about 6 miles away by road. Didn't realise it had the same postcode as us. He did say the house looks very pretty when viewed from the pub
I have cleared the garden a bit, so you can now see the pub garden from our garden - a lot more work still needed.
