The plausible alternative, for some..

Cuba is limiting how much basic fruits and vegetables people can buy at farmers' markets, irritating some customers but ensuring there's enough—barely—to go around.

The lines are long and some foods are scarce, but because the government has maintained and even increased rations in some areas, Cubans who initially worried about getting enough to eat now seem confident they won't go hungry despite the destruction of 30 percent of the island's crops by hurricanes Gustav and Ike last month.

"Of the little there is, there is some for everyone," 65-year-old Mercedes Grimau said as queued up behind more than 50 people to buy lettuce, limited to two pounds per person.

"I'm not afraid that I will be left without food, but it's a pain to think about all the work we are going to have to go through," Grimau added. "Two or three months ago the farmers markets were well-stocked."
