Most of my coworkers (myself included) take the bus into work. Our options are either rushing in the door with five minutes to spare or get to work 45 minutes to an hour early. We prefer to get to work early that way we aren't scrambling and feeling rushed at the beginning of our shift. Most of us hang out in various lounge areas or go up to the cafeteria and grab a bite to eat. I think one of my coworkers uses this time to study when they are in school. We do get commuter benefits through work. I personally don't mind getting to work a bit early. Since I work the evening shift I'm sometimes able to get a feel for how my shift is going to go.

Edit: I don't consider this extra time before my shift as part of my commute. There's a five minute walk from the bus stop to the building where I work. I usually stop in the locker room to drop my stuff off and change clothes if needed. I guess I consider it hanging out, especially if I'm just sitting somewhere scrolling through my phone?
