At 5:50 a.m. on a Wednesday in late June, the sun just peeking over the horizon, Larry Askew woke up in the front seat of his Nissan Sentra. The Sentra was parked where it is every night: in a lot across from Wegmans on Wisconsin Avenue NW in D.C. And once he woke up, Askew did what he does every morning: stuck on his black plastic glasses — missing an arm because he’d accidentally sat on them — drove across the street to the Wegmans parking garage, opened the Instacart app on his phone and started scrolling.
