A passenger has lost an object and we will receive a reward if we find it, a passenger wants a photograph and if we take it he will reward us, a rich passenger has arrived unexpectedly and if we accept it he will give us many bills.

Hehe! This is so realistic and fun. It's appealing to all ages I think, but more adults for sure because we can let our imagination run wild.
I think this is a great brain-trainer:)))
