Diplomatic property cannot be entered or searched (including vehicles.) Getting him out of the car onto the plane may be an issue though.
McDonaldsâ(TM) uses 100% chicken breasts for its chicken nuggets for both the US and Canada (I suspect for the rest of the world as well but I donâ(TM)t know that for certain.) That does unfortunately mean they use the skin as part of it but once in a while it is not bad to have some chicken nuggets. Some of the cheaper supermarket varieties do use mechanically separated chicken but if you look at the package it is listed there and you can avoid those.
Read some other novels from the 1950's and you will see how different it is from other books of the time. Yes compared to current novels it is somewhat underwhelming but compared to its contemporaries it is something completely new.
I think regardless of how in the right the DHS rep is they handled it poorly. If they don't have the authority to change the form fine. If they must seized the boat fine. Explain the the gentleman why you are unable to make the changes and why you must seized the boat. Then let them know what the next step is to get things sorted out. Most people are fairly forgiving of inconveniences if they know why they are happening.
This just smacks of a functionary that enjoys being a pain. As for the DHS agent this is probably not going to go well for them. Even if it doesn't cost them there job it will probably result in a demotion.
Having been to Disney world this past august this is just a more advanced version of the system they currently have in place. The only real difference is you currently use your park pass and buttons (personal event greeting) instead of an wristband. The new thing is pre-booking some ride times which considering the lengthy wait times on some of the more popular rides (2 hours+ some days). Disney constantly tracks ride times, guest flow, guest approval and a whole host of things we would never think of all to improve the quality and safety of the experience to allow you more time in the shops and restaurants where they make the real money. Disney above all is into selling you as many of those trinkets and meals as they can manage. The rides are there to give you a reason to come back.
As for the other issue mentioned (scanning your finger print) it is to prevent people from buying one yearly pass or multi-day pass and renting/selling the use of the pass. Neither of which I can blame them from wanting to prevent as this does cut into there bottom line on ticket sales and skews park numbers.
