Not as such - I think the state pension only goes direct to your bank account now, although the Post Office does offer a pretend account specifically to receive pensions and benefits to those who are unable to obtain a proper bank account.
That said, I think old habits die hard. Round here, at least, Thursday's the day when the oldsters descend en-masse upon the local post office with the sole aim of withdrawing cash and get struck down by a contagious amnesia rendering them unable to find their debit cards, locate the slot in the counter-top chip-and-pin machines or remember their PINs.
They then have to spend the next 48 hours at home, slowly recovering from the trauma of using using modern technology to withdraw money. This lengthy recuperation results in their weekly trip to the local supermarket to spend their cash being delayed until Saturday morning...
"Ooh, this is terrible - I don't not never seen Sainsbury's so busy. It were never this crowded last Saturday..."
