Lefty's is a dilapidated building that neighbors Sam & Max's Office alongside Sybil's. Not much is known about it or its owner aside from being a tool rental store, with Max mentioning that he poked Lefty in the eye with a number 3 socket spanner.
Lefty's plays a crucial role in Reality 2.0 as it introduces the freelance police to the C.O.P.S, who are residing there to hold computer obsolescence prevention meetings, only for them to find out that it has actually been turned into a control room upon visiting its virtual variant.
After the Maimtron 9000's rampage in Ice Station Santa, access to Lefty's is cut off, and with the C.O.P.S. migrating to the Pimp Le Car garage, it is safe to assume that Lefty's is abandoned to this day.
