I think a better analogy is a bank. Imagine going into a bank to ask a question about your account and being told that you have to toss a gold coin in a pot before they'll speak to you ... or even going into a Vodafone shop having to toss a gold coin in a pot before speaking to someone. That would soon drive away customers.
Or going with the New World analogy, this is like taking that dodgy salad back to the Customer Service desk and having to toss a dollar in the pot before they'll even look at it to consider if they will give a refund.
We're talking about customer service, which doesn't equate to a checkout chick, so the original New World analogy doesn't quite work.
