Problem Discovery

The story begins when I take a train from Jakarta to Nganjuk. The journey takes around 10 hours with several stops at the big city station such as Cirebon, Yogyakarta, Solo, Madiun, etc. Long story short, the train stopped at Yogyakarta Station for 4-5 minutes. Then a question comes to my mind. 

"Can I buy a gift, food, snack, or something exclusively from Yogyakarta while my train stops at the station?"
