Bobby Bones was driving in the work parking garage when he witnessed a woman dressed in business attire fall down multiple times.
He wasn't sure what this woman's state was beyond the fact that she seemed with it and was dressed for work. He saw her fall once, and then get up only to fall pretty quickly again. He got out of his car during her second fall to ask if she was ok, she said yes and kind of giggled. So he got back into his car, but he saw in his rearview mirror that she fell for a third time. He's really not sure why the falls were happening and he didn't recall her wearing high heels.
Lunchbox suspects it was a woman coming back from a night out and having too many drinks. Bobby was concerned she was having some kind of stroke, which is why he got out to help her.
