Late night grocery stores

There's a late night grocery store on my way home. I hardly ever use it, but I appreciate that it exists. In that sense, for me at least, it's similar to a falafel restaurant. Tonight, however, I got the chance to use it. Wandering home from a late movie, I got a jones for orange juice. But where can I possibly get orange juice at one o'clock in the morning? Quite simply, I can get the orange juice about one block away from home, on my path from movie to bed.

Most of the time, the late night grocery store is a service I don't feel the need to use. Even though I seldom use it, it's something I like to have around, just in case I find myself needing it.
