Witnesses at the Frankfurt Airport bar tell TMZ … Shia was super friendly with other patrons and even bought a round of shots for everyone. He especially took a shine to an older lady in the bar … and had some fun when she walked over to say goodbye. Weird fun.
Check it out … Shia turned on the charm big time, saying he wanted to follow her “into the future.” Everyone got a laugh, including the woman … who had her own witty comeback for him.
