When you walk into an Apple store Apple openly invites you to use their computers. There are no instructions on what you are and are not allowed to do on the computers, no warnings against installing software or that specific types of programs are not allowed to be installed. The computers are mostly not locked down, the fact that Apple wipes the computers every night shows that Apple expects customers to use the computers in anyway they see fit. Apple's open invitation to use the computers means it is not possible to "trespass" onto these computers.

An Apple store contains hundreds of cameras, the cameras are prominent features in most of the devices and customers will be aware of them. Customers routinely take pictures of each other, of the employees and everything in the store. While using the cameras, they test uploading pictures to internet services such as email, Facebook, and others. There is no expectation of privacy and any reasonable customer should expect that their picture might be taken and uploaded to the internet.
