Most professional by a mile. That's never in question and anyone who doesn't agree quite simply needs their head either examined or removed from where it's currently placed.
That was awfully polite of me
I think some of the reference in previous posts was along the lines of "Venue x already had a game and offered y as a prize, but now it's the same except it costs $13 more and they now have z as a prize."
The direct comparison was pretty much rating y against z for the same venue.
It's probably fair to say there's plenty of players who don't necessarily care about the ticket (until they win one, mind you) and would maybe prefer the $100 (for example) that used to be on offer compared to a lesser amount and a ticket. Also having the chance to get some of their money back doesn't seem to have been factored in either, but then again they expected to have to spend it no matter what.
