Worst post office in London?

Is the post office/newsagent at the end of Erpingham Road, on the junction with the Lower Richmond Road the worst PO in London? Most days it's half empty with bare shelves and a distinctly lacklustre atmosphere. The till looks like something a child would use and more often than not has about as much change as a kid might have. Don't try to buy anything with a note, in fact don't bother trying to buy anything at all. Anyway, perhaps the owner has other things on his mind than running the shop - word on the street is that his wife is being banged by Mr Naki who runs the kebab shop opposite....
