Not at all - This is a culture that is coming from the older and more senior members. Many are highly educated, and often from privileged backgrounds. And again, this isn't candid, behind the scenes stuff - this is in front of civilians, knowing they're on show.
I realise that it's a very different job, but young British men who worked for Sainsbury's wouldn't expect their superiors to be openly racist, sexist, homophobic etc. Given that the levels of control and pride they're expected to take in things like how shiny their shoes are, it would not be beyond the bounds of possibility for them to follow the lead of those telling them what to do when it came to their attitudes being a little more modern. If anything, you'd think it would be easier, given these young people are expected to jump through whatever hoops are put before them.
