As the train pulled into Peradeniya Junction station in central Sri Lanka, the man sitting opposite me leapt out of his seat and leaned out of the window, placing his thumb and forefinger in his mouth and whistling loudly. A vade seller soon appeared outside, removed a basket from the top of his head and handed it to the passenger. The man quickly pulled out a fragrant fritter along with a small bag of fiery sambol, leaving money behind, and then passed the basket to other hungry passengers, who did the same before returning the basket back to the seller through the window.
