I too, do what
18greens does. I always glide approach if there's nobody else around, or if there's nobody in front of me - for two reasons.
1) I like to get the practice - having past experience with an engine failure at 200ft AGL you can never, EVER be too practised. EVER!
2) I'm lazy at the end of a long working day. I can't be assed flying big circuits and spending five more minutes on finals when it's not necessary.
And I always call "glide approach".
