Stopping for lunch in a town you don't want to spend a night in, usually to avoid family, to get together with people while traveling in between 2 towns.
We took the train from New York to Philadelphia, for a lunchover with friends, picked up a rental car and then drove to Atlantic City, successfully avoiding succumbing to familial guilt.
