I had a similar experience about a year ago. I was dressed for a formal banquet, in my kilt and PC, complete with fly plaid. There was a wedding in another banquet room at the hotel and the two groups were co-mingled (with other hotel guests) at a manager's reception in the lobby. A lady stopped me and said, "Oh, you must be the piper for the wedding!" I told her that I was not with the wedding, but there for a banquet. "Oh, you're playing at the banquet, then!" I told her I was not a piper, but merely attending a banquet. I'm not sure she believed me.

Back to Woodsheal's original point, however, I have not been to the Bingo parade in years. I probably would not go kilted, though, because it's usually too damned cold.
