Perhaps. My dining buddy and I had just attended a food fair, a cafe, and a small restaurant, only one of which relied entirely on the Roman alphabet, and so maybe our eyes were primed to see something in that middle graffito. The strong horizontal line, in combination with the whorls below it, is strongly suggestive of a South Asian script. I can't say for sure, but the neighborhood demographic is a good fit.
South Asian wild style?
