You sleep like the dead until noon then suddenly wake up, fully alert and extremely hungry.

Immediately, you realize your predicament. You have no cash, only travelers cheques, and it's Saturday, thus the banks are closed.

Not understanding the apartment heating system, you take a quick, cold shower and ponder your choices on how to feed yourself. There aren't many.

After the shower, you decide to:

wander about the city, hoping to find a restaurant that takes travelers cheques.

go downstairs to the school and hope there is someone there who can help you.
