When they ask what you want, don't say anything about services, the correct answer is "an hour" or "a half hour".
Note that you'll almost never get an hour - as soon as you finish, they usually push you out the door.
If it's slow and the girl likes you you can get extra time but don't expect MSOG.
It's next to Planet K at Research and Duval
