"But I was going into Toshi Station to pick up some power converters!" - Luke Skywalker, Star Wars: A New Hope

Luke's answer after Uncle Owen asks Luke to take their new droids into the garage and clean them up before dinner.

Toshi Station: Anchorhead is a quiet town founded by the original human settlers on the edge of Tatooine's Dune Sea. It continues to serve as a central trading site for desert dwellers whose livelihood is moisture farming. Anchorhead's water and power distribution are controlled by Toshi Station, a small building on the edge of town. Since its earliest days, Toshi Station has been a gathering place for bored youths, including Luke Skywalker and his friends.
