You want to see something funny? Watch what happens when they go back up the list with the "take it or leave it" offer and then no-show the class. I'm betting no-shows will be 50% or better on recall classes staffed on the way back UP the list.
If the class isn't until August or September, why tell them "no thanks" right now? Accept the class and hold on to that last possibility for as long as possible.
yeah, wonder how many guys are going to say yes, then not show just to spite the company.
