Having served a three-day sentence for his drunk-driving conviction, former NBA star Charles Barkley admitted Tuesday he was having difficulty adapting to life outside of jail and to his new low-level job at a local Foodway supermarket. 'I can't believe how fast things move on the outside,' said Barkley, who sat on a park bench feeding birds as he recalled the respect he received from fellow inmates during his time as the jail's librarian. 'Bagging groceries is difficult work, and I try to keep up, but my hands hurt most of the time, probably from my basketball days. I don't think the store manager likes me very much. I wish I still worked at TNT.' Barkley was reportedly last seen in the bedroom of his halfway house, wearing a suit and standing on a wobbly table while carving the words 'BARKS WAS HERE' on a wooden support beam.
