Take your pick. all are safe. Now service? That is another question. How about this scenario we all can relate to: You go to a your bank, customer service for any request, only to be told "Oh we dont do that, you must go to 'your branch' ". Nothing irritates me more than this 'your branch' gig. Meaning only the branch you opened your account at.
When is Qatar going to get a bank that you can request any service at any branch , "your branch' or not.
Anyone here in banking, impress your boss with this forward thinking thought and get a raise. the first bank to do this will have a monopoly.
