I was thinking more along the lines of the weekend when people say they'll be back all the time. But weekends mean other things for people after they grow out of the single stage.
If weeknights, why wouldn't they just stay there after work? Very few move into the burbs just because of work in the suburbs. These are still city job people we're talking about.
If you stay out after work it's still going to take you another hour to get home on the train (when you consider getting to the train, taking the train, and getting home from the train).
It's easy to say "oh, just stay out after work" or "oh, just take the train in for the weekend". The reality is it almost never happens, single or attached.
