Shakes is the Federalist Lounge's robotic bartender, and he dutifully serves drinks twenty-four hours a day, seven days a week. In fact, being a bartender is all Shakes has ever known; he was commissioned by Allistair Tenpenny for that very purpose. Shakes doesn't have much to say, but he can offer discounts on drinks if you know which buttons to press.
If the Lone Wanderer convinces Tenpenny to allow the ghouls to live at the tower, Shakes will survive after the ghouls "purge" the tower of its human residents. Apparently, Roy Phillips does not find killing Shakes necessary, as he is not human.
Initially, Shakes serves drinks at some of the highest prices across the Capital Wasteland. However, if the Lone Wanderer hacks into his programming terminal, his prices can be lowered significantly. The terminal is beside him on the bar and if hacked into Shakes be set to either sell at a "Holiday Discount (10%)" or a hefty "V.I.P. Discount (50%)" (but not both). If the Lone Wanderer is caught doing this, Shakes and all the bar patrons will become hostile. After hacking his terminal and setting up the V.I.P. discount program, his demeanor will change, addressing the Lone Wanderer as "Sir" or "Ma'am," depending on gender, and telling them what an honor it is to serve them.
If the Lone Wanderer engages in a fight with security guards (killing them will give negative Karma), Shakes will attack the Lone Wanderer, but killing him will give them no negative Karma.
