Oh no, my iPad is personal and till now I've only used my home network
I see. I can't think of anything else, besides the Restrictions Settings already mentioned, that would lock your location services to on.
The only other thing I can think of to try is Reset All Settings under Settings > General > Reset. This won't delete anything, or change your account settings. It will default many other settings like wallpaper, sounds, and possibly location; so you'll have to re-tweak when done.
