On the real.
The employees are trying to rush through the mass. They have the setup the phone, activate and etc for the account that they don't have the luxury of time for you to enjoy the unboxing experience. It is unfortunate for those who enjoy it - sure. But it is what it is and business is business. There are a hundreds of customers waiting and want to play with their phone and so they have to blitz through to fulfill every customer.
