Sometimes the Stanley Cup Playoffs make us do abnormal things, like canceling a pizza pickup order because our favorite team just tied the game in the third period. Other times it brings two fanbases together.

This was the case for Catherine Farish from Jacksonville, North Carolina. Originally from Boston, she moved south because her husband is a sergeant in the Marine Corps. She's also a big Boston Bruins fan. Working Sunday night at a local Buffalo Wild Wings during the Pittsburgh Penguins/Ottawa Senators double overtime game, she encountered a customer who would end up making her day.

Here's Catherine:

Last night during my shift this young man came in alone and sat at my table. He was quiet, but friendly and very easy to take care of, he came in to watch the Penguins/Senators game. As we all know it went into double overtime, so he was there from beginning at 7pm to the very end around 11:45. After I congratulated him on the Senators win, I stepped away and during that time he left and when I returned to clean off his table, I picked up his credit card receipt (pictured below) It absolutely made my night and even though I may be a Bruins fan, completely restores my faith in humanity. It was such a kind gesture. Hope this brightens your day!! Thanks for reading!

What she found was a $50.33 tip and this message:

(The "KCCO" stands for "Keep Calm and Chive On", a reference to the recently revived "Keep Calm and Carry On".)

Farish added that the generous customer said he was born in Ohio and raised to dislike all things Pittsburgh (Browns fan, perhaps?). We wish could have seen his reaction after Colin Greening's goal Sunday night.
