In the case of the LHSwhere you were getting bad service. In cases like that if you are dealing with an employee you need to ask for the owner/manager. If it's the owner/manager that is acting that simply tell him that you have money to spend and if he's not interested in taking it then walk out the door and tell him to have a nice day as you walk out.

Hope this helps
