WTH! Am I missing something about negotiations?

[Bluebird Hewitt]

I understand that there is a nominal token fee to make the negotiation, anywhere upwards of 5 tokens,
BUT for example, When I offer money and tokens with the slide bar and put 5 tokens, in addition to the 9 tokens to start, it goes to 19 tokens.

Am I wrong in assuming that it doubles your token cost? because that is what is happening. It says it will return 19 tokens.

WTH? Am I missing something. I read up on the negotiations but seemed to have missed an important factor.

Nordeus says hello to some of those tokens. As far as I am aware, you give a minimum anyway to make the offer, but any increase in offer will give 2T, one extra to the manager, the other to Nordeus, hence the big increase when you make your offer.
