I have to say Lord Sugar's "I wish you well" with Edna may have probably been up there with his "with regret".

Glenn got a "with regret" that was cut. Don't a good number of "with regrets" get cut & saved for You're Fired?

I've always had the feeling that he probably gives almost all the fired candidates bit of a pep talk which is cut because it would sap the drama from the event.
