In a properly functioning company, employee feedback on the complexities or incidents - or direct customer feedback - should be driving training and 'refresher training' needs. It wouldn't be difficult to send a memo or route specific employees into a CBT or classroom to address any confusion.

"Don't just look at status" for entry would be a nice reminder, too. As noted above, you have folks with an F ticket being turned away (initially) from F lounges - that's wrong.
