Dealing with Security people and honesty ??

I was asked to present a Security system to a Yacht in Hamburg, a big boat, when I was able to board the Yacht and propose a system that i was sole supplier at that time for a Dutch company, after having shown all, I left the Yacht in question and drove the thousand Ks back home, where a few days later the company with whom I was working in Holland informed me that the deal was on but the people in the security department of that BIG yacht wanted the system as long as I was out of the loop, thats an extra 20% for them I suppose. honest people I met in Hamburg, so if you have dealings with those people in security I warn you that honesty seems lacking in all departments, and if I need say more I will in public about the attitude of some, have a nice day.
