So the first or the way that I would deal with a difficult customer or situation would just be to step back for a second and to assess what is going on and to make sure that I am keeping myself as calm and collected as possible as looking to not escalate the situation farther than it needs to be. Just making sure that I also reiterate what the customer is saying in terms of if they have any negatives or if they have any concerns making sure that they're heard and reiterating those concerns and problems to make sure that they understand that I know what their problem is and that I'm only there to really help them out and if for any reason it that still that approach does not work of course I would go ahead and partner up with senior management or any management of available to assist me with the situation.
