Where to Find Moxxi
You'll need to advance through the main campaign until you reach the Wrath of the Ripper Queen mission. During this quest, you'll receive the objective "Go to the Bar," which leads you directly to Moxxi's Bottoms Up! establishment in the western section of Carcadia Burns.

The bar sits prominently in the Ruined Sumplands area, making it impossible to miss once you're in the right zone. The tip jar itself rests on the main counter, just waiting for your generous contributions.

You cannot interact with the tip jar until you've progressed to this specific story mission. Don't worry about missing it - the game naturally guides you here.
The bar's central location in Carcadia Burns makes it easy to return to whenever you want to try your luck with additional tips.
How To Unlock Glucose Guardian Achievement
Your first tip of any amount automatically unlocks the Glucose Guardian trophy/achievement. This bronze-level reward requires only a single interaction with the jar, making it one of the easier collectibles in the game.

How the Tipping System Works
When you approach the jar, you'll see two tipping options: $100 or $1,000. Here's what makes this system unique - the amount you tip doesn't influence your chances of receiving a legendary weapon. The reward system operates on pure random chance, meaning you could get lucky with your first $100 tip or need to invest several thousand before seeing results.
Watch for the Heart Animation
Success is clearly indicated when flying hearts appear above the tip jar. This visual cue signals that Moxxi is about to reward your generosity with one of her special weapons. The animation is unmistakable, so you'll know immediately when you've hit the jackpot.
