I think it's important to remember
Nor1 is
not a Hilton product - it is a product formally called
eStandby Upgrade® -sold to Hilton by a third party vendor, and used only with some brands. The main taglines include "Nor1 - Travel Industry Upsell Technology" - and "Upgrade Your Life".

(If I weren't polite, I would use the tagline "Go upgrade yourself", or something like it.)
But I suspect HH in its infinite wisdom of curtailing training has told very little to HH personnel and local clerks just deal with it as it happens. In all,
