Shakes

 is a Protectron robot that functions as a bartender in Tenpenny Tower. Initially the priciest bartender, he can be hacked from a nearby terminal to offer discounts up to 50%. With a moderate barter skill Shakes can become one of the most cost effective places to sell loot, except for its low amount of caps. Also, it should be noted that if you are caught hacking the terminal and lowering the prices, all NPCs in the room will become hostile.
