People don't refer to contracts often, and we intuit costs all the time. We have many services and utilities which are pay-for-what-you-use, such as gas, electric and internet. I don't know how much it's going to cost me to turn on my tv, but I have an intuition it's not enough to prevent me from doing so. I don't look at the price of most of my groceries. I just do a mental "looks about right" at the final total before paying it. And none of this applies to a 14-year-old, who no one should expect to read a contract to figure out that normal use of a device will cost thousands of dollars a month.
