The marketing strategy behind promotional kids meals isn't even close to papering, and to pretend that it is is an insult to both our intelligence.
It's actually ingenious, if not morally questionable, to use cross-promotion and a literally valueless toy to incentivise children to influence their parents to buy the family dinner from your fast food place over the competitions. Note the bit about buying the family dinner, i.e. everything is paid for.
An equivalent strategy to that would be for the Eels to give away a cheap piece of merchandise with every sale of a kids ticket, or something similar, in the hope that kids would beg their parents to take them to the footy to get the toy. But I digress.
Something given isn't valued either. Those kids are going to grow up not understanding the actual value of admission and will think the true cost is unreasonable, which is exactly what ends up happening when theatre, festivals, wrestling, circuses, and other similar businesses, paper the house too often. Supporters = customers in this context, and customers that become entitled to the product for free, or so cheaply that the business can't recoup costs and hopefully make a profit, aren't very valuable...
Whether or not the NRL currently values membership numbers, or ticket sales more generally, is pretty irrelevant from the argument as well. They should value every revenue stream, they should be looking to maximise every revenue stream as much as reasonably possible, they shouldn't allow any of their clubs to undersell the product, and the fact they don't do any of the above is just one of a myriad of reasons why competitors like the AFL and it's clubs are so far ahead of them.
