A receipt from the restaurant posted online shows Manning gave a $200 tip on a more than $700 bill.
However, if you factor in the 18 percent gratuity that was already added to the bill, it actually means manning left a 50 percent tip.
Manning was in the Triangle last week with some former teammates.
However, there's a twist to this story. The Triangle Business Journal reports the Angus Barn has fired the server after learning the check went viral. They said it goes against their policy.
