Shenwen didn't say anything about letting kids bet. You seemed to have pulled that out of thin air in your desperation to invent things to argue against.
So Scrambler's recently had kids. There are all sorts of sacrificies and curtailments to lifestyle when that parents make when they have kids. Not being able to walk into a Jockey club while carrying a kid in order to buy a Mark 6 ticket is about as trivial as you can get on the scale of such things... to the extent that anyone would be hard pressed to call it a 'sacrifice' in the first place.
What next- complaning about not being allowed into a pub to buy a quiet pint when carrying a five month old? After all, it's not like the kid is going to start downing vodka shots, so what's the problem?
INXS pretty much nailed the reason for this prohibition being a good one.
We really need a "First World Problems" subforum.
