A postmistress says customers turn 'abusive' when a full range of banking services are not available.
BBC Norfolk political reporterTina Kelly, who runs a branch in Norfolk, said that since local banks had closed, the increased in customers had been "phenomenal".
The Post Office said it always reviewed the provision of banking services at branches where demand had increased. It said its 11,500 branches had seen "unprecedented growth in demand" for banking services and had supported £3.3bn worth of transactions in the UK in July alone.Ms Kelly, who runs a small post office counter in a town where several banks had recently closed, said she had worked in post offices for almost 20 years and that she "loved being part of the community".
"We can't cope with the demand. It's very stressful on our mental health... and physically," she said.
