Performance art or not?

Ok so with Easter and everything, I came about something that I couldn't figure out. Wellll, outside of one of the stores in my town, there was a person dressed as an Easter Bunny pointing for everyone to go inside and obviously an advertising scheme by the store. But then i thought to myself, is it possible that the person is actually putting on a performance. Although the store told the person to go outside and stand there to attract customers, it is up to the person in the costume to put on a unrehearsed and unique performance with hand gestures and dancing while wearing this suit that is clearly not him/her. So would this be considered performance art in a way??
