Why are managers in the field? Because they produce nothing. Generally, a manager is simply someone who has compromised their principles and had the unique ability to say yes. If you want to break their chops, especially if they have driven hours to get to you/ is to work until 5 and then ask to role play because you are not comfortable with the sales call. Another good strategy is to bring epicac with you, Go to the bathroom and take a dose. Go back to the table and vomit in front of them. Youcan also ask them to take a sales call. They will panic.
use the Socratic method and answer all questions with a question. Ask them to explain the difference between an assumptive close and a reciprocal close and how it affects the effectiveness of the presentation. Its also good to drool occasionally and complain of back problems.
You can also pull the fuse in one of the warning lights in your car. It will not be safe to drive and its doubtful they will want to hang at the garage with you. They probably have a conference call to get to. After having too many managers to count its as simple as this. They all talk a good game but do they show up on time, are they willing to stay late in the field, are they there to help you or critique you. What do they talk about? Break their balls because they are not that smart they are simply tools!
The ONLY thing that matters with this job is expense reports. They never let anyone go due to poor sales because its all BS. Why have CEO and forced rankings? Expense reports matter because they are the only factual things you deal with.
