Envoys from the European Commission, European Central Bank and IMF descend on Athens Monday to see if Greece is worthy of receiving its next bailout installment. If the international community concludes that Greece can't be saved as a member of the Eurozone it will have to revert to its old currency, the drachma, which some say would be "catastrophic."

Austerity measures imposed by international lenders in exchange for billions in bailout loans have cut deeply into Greek pockets. If Greece defaults on its massive sovereign debt, it may be forced to leave the Eurozone.

Yet despite the scores of anti-austerity protests outside parliament, polls show that up to 80 percent of Greeks want to stick with the euro and avoid reverting to the country's old currency, the drachma.

"The drachma would be catastrophic," says Dimitris Dimonopoulos, the 43-year-old owner of Souvlaki Bar, a restaurant near the Ancient Agora in central Athens. Many of the restaurants in the area close early because they don't have customers. A quarter of businesses in central Athens have closed because of the economic crisis.

Souvlaki Bar is holding on. It combines cheap traditional food, including the marinated kebabs called souvlaki, with the sleek decor of a European bistro. Dimonopoulos says his business is doomed if Greece reverts to the drachma.

"I import my meat from Denmark because Greece doesn't produce enough," he says. Greece imports far more goods than it exports. The cost of imports would skyrocket under the drachma, says economist Panos Tsakloglou.

"For firms that are importing, the situation will be kind of dramatic in the sense that nobody would accept initially drachmas," he says. That's because if Greece left the eurozone, the immediate transition would be difficult.

"If you want to use drachmas tomorrow, drachmas do not exist," Tsakloglou says. "You need to mint coins. You need to print banknotes and so on. And all these things are not available right now."

The drachma would have no price during this chaotic period, he says. People would run to banks to withdraw their money. They would clean out supermarkets, where most goods are imported. They would also flock to gas stations, since petroleum is also imported.

And once the drachma is established, he says, Greece would be left with a devalued currency.

A devalued currency would help people like Yiannis Yiagos. He makes wooden donkey puppets and sells them at a stand near the Ancient Agora. He points to one puppet, which he makes for one euro and sells for five.

"He cost one euro and sell it five, because it's the euro," he says. "If I had drachmas, I take one drachma and I sell two drachmas."

Yiagos explains that tourists say five euros, which is more than six dollars, is too expensive. So he wants the drachma, so his donkey puppets will sell. He says more tourists will come if Greece is cheaper.

Christos Tsoutsas, who runs a metalworking shop near the Ancient Agora, is also struggling these days.

"I have a big mortgage and I can't pay it," says Tsoutsas, who is 65. He's bundled in a puffy brown coat and sitting near a small heater. His store is empty. "Look around here, I don't have customers," he says. "And I don't know what's going to happen."

Panos Tsakloglou, the economist, says proponents of the drachma claim people like Tsoutsas would benefit if Greece left the euro.

"They hope once we return to the drachma they will repay their loans in drachmas rather than euros," Tsakloglou says. "This is a big 'if' for different reasons. I mean several of our banks have taken loans from abroad. In order to repay these loans, they need euros."

And the Greek state would have to pay much of its own debt back in euros. That means a much bigger debt in drachmas, he says.

Tsoutsas, the metal shop owner, says he doesn't want to take that risk. He wants the euro. So does Dimitris Dimonopoulos, the owner of Souvlaki Bar.

The euro is not just about money, Dimonopoulos says.

"It's very important for Greeks to feel like they're part of the European economy," he says. "How terrible would it be for so many people to have worked this hard for so many years, to have dreams in a country that won membership into the European Union — and then to lose it all."
