You will get lots of different views on this because we are all beautifully different. Me myself, no, clients have never messed up my relationships, tho I have had a argument a long time ago because one of my clients turned up on the door and my partner answered it. This should never happen, clients should NEVER! turn up with out an appointment, and it really annoyed him, but after he huffed and puffed he realised it wasn't my fault but the clients.
