T.I. left a generous tip for servers at Abe & Arthur’s on West 14th Street after dining with rapper Gucci Mane and Selita Ebanks — and he also left his “permission to travel” papers on the table. The document verifies that the rap star can leave the United States for a specified period. T.I. is on supervised release after doing prison time for weapons possession. Luckily, a restaurant employee returned the papers to T.I.’s security guard before the crew headed downstairs to club SL. A T.I. spokesman said, “He did not leave behind any documents.”
