Unexpected biking sight:

Late at night just west of downtown, I see up ahead a utility service van near an uncovered manhole where there are lines going down in and pumping stuff out, and as I bike by the van with its back doors wide open and its back part all lit up inside, there's like 4-5 workers in the back in hard hats and orange and neon green vests sitting down in there and eating their lunches (dinners?).
