Stupid Installation Disc

Client: I need administrative rights to install software.

Operator: A tech is not presently available, but I will have them call you back.

<Time passes…>

Client: You can install the software today at noon.

Tech: I will remotely connect to the system at that time. Thanks!

<Client takes installation disc out of computer and puts it on the shelf to keep it safe. Disc drive is used for nothing besides installing this stupid software.>

Tech: So… where’s this disc I’m supposed to install the program from?
