I've got a bit funny situation.
I wanted to make small application to speed up my dad's job, app is about duplicating models in X website (I don't want to say directly what website).
So I started by checking it has API, Yup, It has, but you need OAuth ID, to get it you need to write to support.
So I did it, my mail was something like that: "Hello, can I get access to your API, I want to make app to duplicate models with same settings, Thanks"
I've got an answer like that "Hello, our website doesn't have duplicating feature."
My reaction was: Wtf? I know it doesn't have that feature, That's why I want to make it. How did he get hired as technical support?
Maybe it's not the most exciting story, but I thought it could be intresting :)
