Sidney Crosby and Nathan MacKinnon work the drive-thru at Tim Hortons

Some lucky customers stopping by the Tim Hortons in Dartmouth, Nova Scotia, on Monday received quite a treat. And that was in addition to the iconic Canadian franchise's coffee and donuts.

Pittsburgh Penguins star Sidney Crosby and Colorado Avalanche center Nathan MacKinnon were on hand working the drive-thru, and surprised customers while shooting a commercial for the chain.
