Yes, it's a rhetorical question.
Here's a few things to remember if you decide to go for the upgrade:
#1) You actually have to give them the money

#2) Don't be too discreet
Once I finally decided that I wouldn't be branded a degenerate for following the rules of the trick, I started putting the $20 between my license and credit card. At the beginning however, I didn't really realize that the idea was for the front desk agent to actually see the money. On one attempt I folded the $20 bill so neatly that there was no part of it visible. Unfortunately I was a frequent guest at that hotel back then, so when I slid my I.D. over to the clerk, he simply waved it off saying that all my information was already in the system. I had to insist that he verify who I was before I got a chance to ask about an upgrade.
