Is this the best beer related celebrity sighting ever? It has proximity, exclusivity and... royalty:

About a minute later, who walks out the door but the Queen! She’d been attending a meal with the Privy Councillors and was leaving the building. As she exited, she stopped to say something to someone. Her gaze fell upon my buddy and me. She looked at my red running shoes, then the beer, then back to my shoes, then up at me, smiled, said something that made those near her smile, then got into the car and left.

Her Majesty having a laugh at your expense has to be one for the record books. Not that I am in the Monarchist League's Rolodex or anything but you have to respect the "oh dear, a loser Canadian kid with a case of beer" response.
