@Layman, I have many accs with them and they are not perfect - rigid, process, selective...
But I'll tell you they're one of the most efficient banks I know and very professional. With 44% increase in profits in a recession year, the idea of bouncing cheques for fee income is laughable. Th reason can only be their rigidity and 'protecting their customer'
Come to think of it though, all bounced cheques state a reason. What are the reasons you're seeing on these cheques?
