Speaking as someone in a relatively isolated village, I'm a big fan of the local post office. They shouldn't be looking at closing them down but expanding their range of services.
"Give us more services!"
"Well thats up to AnPost to sort out"
There arent services for them. Do what the Scandinavians do, post offices are a second till at the local Spar equivalent. If you dont need a spar, you arent big enough for a PO. End of.
Added bonus: you can collect your parcels until 9PM, not 9-4.30!
