How can you turn down free?!
I felt the same way, what's the point? Right until my photographer told me he'd throw mine in for free as well... then I said, what the heck!
I did mine yesterday in Downtown LA, 104 degree heat inside Union Station, no AC. So it was uncomfortable but I had SO much fun I'm shocked at how amazing the experience is. It's photos of us young and in our 20's I'm going to love showing my kids and grandkids one day and it was free.
I say if you can convince him to just have fun with it then definitely go for it!
