Have you ever set aside time to meet with someone and, after just a few minutes, you realized the meeting was likely a waste of time and didn't need to continue?
In certain situations, such as an internal meeting with your team that concludes early, it's easy to dismiss everyone and give them time back into their day. But sitting through a meeting that has no point in continuing, such as a job interview with an unqualified candidate or an appointment with a prospect that has no interest, can feel incredibly awkward, especially if this meeting was originally intended to last much longer!
One way to combat this is by setting expectations beforehand with a strong up-front contract.
