Former Vice President Joe Biden snapped a photo with Denver International Airport employees after getting his shoes shined on Thursday afternoon.

DIA tweeted out a photo saying,

"Even former Vice Presidents need to get their shoes shined at the airport every now and then."

Biden responded a few hours later, writing

"One of the best shines I've ever had."

The former VP is in Denver for his 'American Promise' tour to discuss his new book called "Promise Me, Dad."
