Lasanda Deepthi, a 43-year-old Sri Lankan woman, plans her day around fuel queues.

As the driver of an auto-rickshaw on the outskirts of Colombo, the commercial capital, she keeps a close eye on the gasoline gauge of her sky-blue three-wheeler before accepting a job to make sure she has enough fuel.

When the needle is close to empty, she joins the line outside a gas station. Sometimes, she waits through the night for gasoline and when she does get it, it costs 2.5 times the amount it did eight months ago.
