Felt like a scam

I went on this trip with a few of my friends from a local leadership club. We were there to help out and be with the community lots. Those were the two things we didn't do a lot of. I imagined we'd be with the kids and they'd help us with what we were building, but sadly we were limited to one hour of interaction with the community we were building for. Overall the experience was good, I just felt we got scammed, as the facilitators and staff were always hiding stuff from us.
