Consultant Slow

Hi I am really fed up with the consultant on station 3. I don't know why he always so comfortable with clients that he waste long time opening account for a client, especially if the client is a woman. I also experienced his comfort zone last year. I am writing this to know how to deal with this guy wearing spectacles on cubicle 3. The manager is always helpful, I can see she is able to work under pressure and always busy. But the consultant on cubicle 3 is too comfortable to understand customers can't wait more than an hour to be assisted

Is it possible the manager be told? but I didnt want to vent as she so helpful and very productivity and I understand I'm not the only client in the bank.

Please get back to me I need answers, what action should I take?
