As always, you are walking around the city center with your friend. You have already tried all the options so as not to get bored, but in the end you have no ideas left

At a completely random moment, your friend stops with sparkling eyes, and points at the guy at the other end of the square

"I came up with it! Bet you can't get this guy's phone number?"

You rolled your eyes. Her ideas cannot be abandoned.. But you can't just approach a random guy like that! Or can you...?
