TIP: Do a three-count to help your timing on the stop. Like count 1 as she goes by once, then 2 as she goes by a second time, then stop it on her third go-by when you count 3.

Watching her go by twice will help you time your stop on her third go-by a lot!

Fun distraction for all of a minute. Would be a great minigame in those boring RPG casinos though.
