Scarily.. he was a taxi driver at the time. If she was looking for a ride home.. she could have stepped right into this guys cab..
Harrington went to use the restroom at the arena and somehow wound up outside the gates where she was refused re-entry (I hope that employee sleeps well at night). She texted her friends her dilemma and that she would find her own way home. It was October and cold outside so I'd guess a taxi cab was the first number she called.
