Yeah, I have met hundreds of those. And they never learn. Well perhaps they do, but there is lots of others standing in the place to replace them. Anyhow free cargo of 3000 units as a refund for me. But in the other hand most of the time it doesn't make up for it if you do not find with who to actually roleplay.
The most sick part is, they give you 500 cargo from 1200 requested, and later run away saying "I paid u can't keel me"
