I was doing the security there many years back & we had to draft in any Tom, Dick & Harry to cover the venue,
We couldn't be too fussy as it was a rush job but one guy
(who was recently over from Africa) refused to wear any footwear & wore his tie on his head!

(TRUE)
So he was walking around barefoot with a tie on his head speaking very broken English.
(& tbh he was one of the better security guards we'd recruited !)
