A casual friend of mine once tried to get me into some MLM operation. He called me one night, telling me he had something really urgent and important to discuss with me, but wouldn't say what it was on the phone. He asked me to meet him in the city centre the next day. I went, as I was worried - he'd sounded stressed on the phone, so I thought he was sick or in some sort of trouble. I saw him, we greeted and then he introduced another man (with over-trendy haircut and expensive-looking clothes) to me.
We then went into a cafe, where the other man flipped open his briefcase and started presenting this wonderful business scheme that I'd only have to pay 100€ to get into at beginner level. I was so confused about the whole thing that I listened to the spiel and told my friend I'd think about it when they pressured me into joining right away. My friend then called me a few hours after I'd left from our charming get-together, reeeally pushing me to join. I refused, and haven't really seen the friend since.
The business scheme was in the news about a month afterwards, as it'd been declared a pyramid scheme by the officials and thus was illegal. I think the man who did the talking during my recruitment attempt was sentenced to at least fines, if not jail.
