Across the country in Hingham, Massachusetts, Jeremy Johnson of Encore Specialty Food Importers is also facing transaction issues.
While the food importer is still receiving shipments from Greece, Johnson is worried some of his Greek suppliers may start to ask him to pay for goods in advance to hedge any capital flow problems in Greece.
"If we pay that [cash payment] in advance, what guarantees do we have that the order will ship and will deliver to us?" asked Johnson, national sales manager for the food importer. Johnson made the comments to NBC affiliate NECN.
Johnson said he imports millions of dollars' worth of products from Greece each year. "If it [the supplier] doesn't deliver, for whatever issue, then we're out of the product and out of the cash."
