On Wednesday, Cardinals tight end Jermaine Gresham helped a random stranger out at the airport.
Delilah Cassidy, an American Airlines passenger, had trouble when her bag came in over the weight limit.
She explained on Twitter that she had just gotten back from Europe and couldn't pay the $50 the airline was trying to charge her because her cards were being declined, and the airline wouldn't take cash.
Then a stranger stepped in to help Cassidy.
Turns out the stranger was Gresham.
As Cassidy said, it's always nice to know "there are good people in this world."
