Unscripted action? Well, Mr. Stark, Andromeda Tonks is happy to oblige.
Or rather ... her grandson is, as there is a little boy flying -- yes, flying -- around the bar proper with what look to be very large angel wings.
Totally blaming Carl and Michael for this one, thanks. The woman sitting (mostly) directly underneath of the frolicking boy is tapping her fingers on the bartop and trying not to swear ... or smoke. That much is blatantly obvious.
