At my work we have a frugal tiny core as office workstation, at one occasion the user was not present and three mac users had to turn it off, they all three stud there discussing how one turns off a "PC" as they called it (they all three use their mac laptops as pc). It has a wmclock (fishtank
and 4 icon wbar one icon being power off. One decides to click the mouse button and sees the exit.
Another occasion same workstation one needs to read some files on a usb and boots the workstation up, the wallpaper being a telephone list for the company with logo, names and all confuses him so he reboots just to be greeted with the same desktop 10secs later, confused it just shows some strange "computer" list thingie he gives up. Not seeing wbar nor clock both pretty large at the top.
Writting this I now wonder how he got it rebooted, not sure if he turned it off.
