When dealing with clients and referral sources, one aspect that will always lead to a negative impression is either not being respectful of or wasting that persons time. While you may thing taking a quick phone call during is a meeting is “no big deal” it can most definitely leave a bad impression on the client. Likewise you need to have a understanding of the kinds of cases your referral partners are looking for as well as the job they are expecting from you. You don’t want to waste the time of someone you are trying to do business with.
