Kids can be just as specific as collectors when it comes to wanting a certain toy, however. TRU are doing themselves a disservice if they're trying to avoid helping customers after specific items.
It's a lot easier to p*** someone off and lose their future business than it is to win them back. It's also hard to measure - and limit - the damage to the brand if that parent tells friends about their porr experience at TRU.
I'm not saying that TRU should bend over backwards for customer looking for a specific item, but generally they're quite unhelpful, because of the way they set themselves up. Target & Big W on the other hand, are more helpful - and even if the end result is the same (customer unable to obtain item), the customer isn't left with the bad taste in their mouth.
