I had a meeting recently with an accountant and was led into his office while he was on the phone. I overheard him telling a client that he wouldn’t be able to get his work done as promised because his humongous client needed something done right away, and “you know how that is!”
Ugh! He just guaranteed that the client on the phone would never ever recommend him to anyone. He also told that client he is not important. Additionally, he was discourteous.
Clients understand they might not be your largest or best client, but they’re also very important to themselves and want to be treated with respect and courtesy. They like to be made to feel important. To me, every client is important and I treat them as such—they all contribute to my income and that is also important to me.
