Justification? Shit, my company spent $900 for an airline ticket and over $1,800 for hotel and expenses for me to travel to Seattle to teach ONE student a five day class. I lobbied against it, told them I'd be happy to stay at home and use WEBEX or something to take him through the class online. Nope, the justification was (with respect to Wilmac), "The customer wants it this way."

The customer paid 5k per student for the class, so my company made money. That's all the "justification" they needed.
