This quest on UVHM is the fastest (and safest) way to power level someone in Borderlands 2. Sanctuary has to be in the air to get behind the counter like this, then you just get in the position shown, have your friends join, and you can all just go afk or something. It should get someone from level one to 72 in about an hour and a half. 1 to 10 in seconds, if someone just wants a little head start for leveling or something.
*DO NOT SLAG THE BANDIT OR YOU WILL SCREW THIS ALL UP.* If someone slags the bandit, alt + f4 before the game saves. If you're not sure if the people you are leveling are asshats or not, back your save up first, so if they slag him and ruin your quest, you can just restore the save.
