Supermarkets in Greece were selling out of staple foods today as worried shoppers stocked up on essentials amid growing uncertainty at the repercussions of the 'no' vote against EU conditions to keep the bankrupt country afloat.

Shelves were left empty as consumers stripped them of basic essentials including rice, flour, sugar, dried beans and cooking oil in shops in the capital Athens.

Managers tried to reassure their clients stocks were 'not running out' and proud shoppers denied they were 'panic buying'.

In the well-off area of Glyfada in Athens residents piled everything into their carts from multiple packs of lentils to vast rolls of toilet paper over the weekend.

'Most people are buying food now because they fear the worst,' said 51-year-old finance worker Andreas Koustras.

Retail worker Marilena, added her family was buying 'food, only food, nothing else. Only what's necessary.'

And at the Sklavenitis supermarket, in the middle class district of Nea Chalkidona, shoppers had stripped the shelves of rice and flour on Monday and customers jostled to pick up the remaining bags of lentils and dried beans.

Uncertain: Former airline executive Lefteris, 80, with his wife Artemis, 68, as they picked up supplies at an Athens supermarket. He told MailOnline: 'I don't know where this referendum vote will take us'

The city buzzes with nervous excitement amid growing concern at what the future holds for Greece following the country's overwhelming rejection of EU conditions to continue to bailing out the bankrupt state.

Former airline executive Lefteris, 81, told MailOnline: 'I don't know where this referendum vote will take us. I have no idea what will happen next.'

Grandfather Constantinos Pereolglou, 70, retired agro-chemist, said: 'I was very surprised with the referendum result. There was a big difference from the 'yes' vote. I don't think the 'no' vote is good for Greece or my family.

'My children work in the private sector, the don't work for the government. They work for multi-national companies, they could lose their jobs at any time.

'I'm putting my hope in EU partners to treat us fairly.'

Meanwhile, across the city a retired nurse was forced to queue along with tramps, drug addicts and the mentally ill to get her main meal of the day from a church-run soup kitchen.

Retired nurse Cleanthi, 65, said: 'My income is €400 a month from my pension but it's not enough for me to pay for all of my bills – rent and electricity – and buy food.

'This food has helped me to survive. Today it is nice – chicken and rice. Some days it is not very good. I come every day. This is my main meal. I have my son to look after. He is 33 and unemployed.

'I was a nurse. It was an important job. You have to put your whole soul into it. I paid into my pension for 28 years. But now I cannot make ends meet.

'I voted 'no'. I like [prime minister] Tsipras. I blame all the politicians before him for getting us into this mess.'
