This continually drives me nuts, especially watching people from windows use macs. They want to get normal maximize behavior to not have to manually size a window, and instead get thrown into fullscreen. This causes an immediate wtf moment, asking me how to undo it, and then living with a tiny little window. sigh

Tell them to double click the title bar of the window. This will maximize it for most windows, similar behavior to what they should be familiar with in Windows on that front at least. Sometimes this results in a "smart" maximization, like if it's a PDF in Preview it'll take all the vertical space it can get, but won't widen if it's in a single page view beyond what's needed. You can also hover over the edges (left/right, or top/bottom) until you get the double arrow cursor and double click to extend in horizontally or vertically, again just like Windows offers there.
