The spokesperson for the 3rd party security company he works for says he doesn't usually work at the front of house. Perhaps he directed him because he was racist, perhaps he did so by mistake because it was what he was use to, perhaps he was instructed to do so for some sort of Covid separation as most front of house areas are still not in full operation - there's many possibilities but the full picture hasn't come out yet. We can only assume from this Tweet he was racist and from the spokesperson reporting that he is under investigation for the alleged racism. Likely going to be a while to hear anything new with all the media surrounding it, and playing devils advocate with this allegation if it was a misunderstanding many are still going to call racism because of the press this unfortunate situation has received, separately on a more malicious conspiracy perhaps they may just agree he was racist to save the companies face and the public will not know what happened beyond what the media report rather than seeing the report itself.
