I haven't had Gregs Steak bake as I dont frequent high street bakerys with all that foul mass produced rubbish.

BUT I would be irritated if she asked me that in that stupid over airey way. It's not good practice, its annoying. Its the difference between knowing what works and having an office born 'good idea'.
They ask you in some chain restaurants because they have a system they want to explain, but she was reinforcing their concept.
I'd let it go on day one, if she did it it my 2nd visit there wouldnt be a 3rd.
