For example, fewer executive lunches, more low-key events, and potentially less lavish conferences and Christmas parties.
But while all of these developments are a definite sign of the times, perhaps there has been no more symbolic sight of the GFC than appeared on the Sydney city skyline recently.
It was the Macquarie Bank 'donut' with a quarter bitten out of it.
We're not sure if it's a reflection of the battering the company's share price has taken recently or perhaps the fact it can now only afford to light up three quarters of the donut.
Those who have seen the sight would have to agree it actually looks like someone has taken a substantial bite out of the donut.
We can't think of any culprits off the top of our heads, but it wouldn't be a surprise if an image of Homer Simpson soon appeared on the Macquarie Bank Bond Street premises to make the scene complete.
