I think the postman is late today. Or I got no post.
I should really get in the shower but I'm having a lazy morning and I am expecting a few deliveries that probably would not get through the letter box.
It would be great to have a postie tracker app. Just type in your postcode and it would tell you if letters or parcels have been delivered to your street yet.
Of course - it could be misused by Royal Mail to monitor the speed of a the delivery. And if they've stopped to fix car tyres 
But from a customer perspective - it would be good.
