The Adult Entertainment Industry
A few years ago (OK, quite a few decades ago now - where does it go?) I was in a meeting discussing the possibility of selling product online. It had been decided that we would need to employ a consultancy firm for much dosh to guide us through the process.
In my youthful innocence (All right - many decades!), I asked why we didn't just get in touch with the webmaster of a porn site because those guys had been doing online payments for years.
My suggestion wasn't met with the kind of reaction I'd hoped for.
