If you're based at the outstation, you live there and are at home between arrival and departure time and most of the weekend. If your trip is based at the hub, for anything but a short layover the company provides either an apartment or a hotel room. Folks do different things at during their layover time, and the time is yours, but anything that could make you late for the inbound trip is discouraged. In some cases, your legal rest period is at the layover, and in that case you need to get some sleep!
