If I was stranded in a random foreign city with no friends and no money there isn’t hell of a lot I could do really?
Its a strange question, why am I stranded in the first place? Will things get better for no real reason after this one day?
I guess you’d have to find a police station and tell them that you are a foreigner with no money and not sure why you were there? Possibly ask to use a phone and find a way back home.
Now if my friend had dropped me off in a city on holiday and I’d done something stupid like leave my bag in their car and they weren’t meeting me till later on, first of all I’d find some way to be able to tell the time. There is no point walking around too far if you don’t have some way to tell the time. After that it’ll be as easy as finding museums and churches, historic locations or just beauty spots. You don’t have money so you can’t go anywhere really so it’ll just be hanging about.
Problem is I would never just randomly go somewhere with no money as its a necessity so its hard to imagine a reason why I’d end up stranded somewhere with no money at all!
