It wasn't a secret weapon because it was essentially bought "off the shelf" at the Intamin coaster shop.
It's a bit more complicated than using the express checkout till at Asda (I assume you have problems with those?) - but that's pretty much it.

Intamin said "Here you go"
And off they went... Well, after they got a till assistant to come over and deal with the "Unexpected item in baggage area" error....
With all that noise, no wonder it wasn't a secret
