alighting at the wrong station

I did the stupiest, brainless thing today. I alighted at Bugis Mrt when i am supposed to be alighting at Lavender Mrt for work. (which is nearer) When I realized, its too late and the train doors have closed. So what is the next best plan when the next train is too long a wait for me to arrive to work? I walked from Bugis to my workplace lo. I walked very, very fast in my heels. I can't even remember the last time I give my legs such a good workout haha. Still cooling down phew.
