taking photos for free to friends

Hey everyone!

My photos and videos are above average and actually really good, even though I don't do this for a living. Sometimes, when I'm at events or out riding my motorcycle, I take photos and videos for close friends for free.

I'm starting to hate this because most of the time they don't even thank me or tag me on social media. Even if I don't work in this field, I'd still like to get some credit or promotion. You never know what could happen.

How do you guys handle this situation? What do you tell people when they expect free shots?
