Someone might, but as I was halfway down the WSU stairs at the time it won't be me because I did not see anything.
Neither will the guy I was having a drink with, he uses stewarding to supplement his hugely reduced income since being made redundant.
After having a couple of drinks today, with a guy who witnessed the entire thing, his opinion is the Steward in question is taken to book, loses his job and is charged with assault.
BTW, the guy I was having a beer with is a Steward.
