There is an Indian grocery in town that has a little take-out place attached. Both have been open 24 hours at some points, but currently the grocery is open until 10 PM, I believe, and the take-out place (as you can see from the sign!) is until midnight. It's still later than most things around here.
I don't know if these workers were on their break or had just finished a shift, but I caught them stopping in for some late night food either way.
