That's what I do when my relatives ask for tech support - I'll do it for a home-cooked meal.
Restuarants regularly give away free samples to gain "word of mouth" reputation.
That's the fremium model, yes. I was referring to people who demand that all software is easy and should be free.
They do? News to me. I've never gotten a free penne puttanesca. But I've gone back to my favourite restaurants after 5+ years. And god damn, I do code changes for "free" too. I need to harden up!
