Oscar was da man! I called ahead and asked if they could root my ATT LG G3 so I could enable wifi tethering and he said no problem, come on in. I stopped by 10 mins later and he worked on it while I waited. 10 mins later he was done and now I can wifi tether :)
I called other shops and they were telling me it could take up to 2 days, wtf? Go here, you won't regret it.
