So, Angels should be able to see through a poor presentation and not place style ahead of substance? Agreed - it's in their interest after all. In reality I suspect each Angel has a different tolerance for this, if you spend all day seeing shitty presentations the tolerance is probably tested! There is probably also a range of shitty-ness as well!

Wasting time and effort discussing it at the time or giving public lessons in pitching simply adds another shitty pitch to the day. One that is probably the worst received, ironically!
