That's very kind of you. I did not even think of that idea but it's actually good. In that way, they may search and learn about bitcoin, and because of that bitcoin is again shared to those who do not know it yet.
Have a safe trip, and enjoy your activity for today! Thank you for sharing a new way for spreading bitcoin this day. Let's share some love and kindness today.

But it would be great if they could get the BTC that OP would give since it is a present for them to be used.
