Funny enough, my first attempt at that was for a bakery down the street. I walked in with my laptop ready to show a basic site, but the owner was more worried about her oven timer going off. We ended up talking about her daily routine instead, and I learned that a simple ordering system would help more than a fancy website. In my experience, sometimes you just have to listen first before pitching anything.

So when drew_stone46 mentioned it being hit or miss with plastics, that got me wondering. I had a similar fail with a plastic cup, so it's not just models. What's the actual science behind why some plastics bond and others don't?
