Bill, I don't know WHY they always go along, but I don't really offer it as an option. I tell them that is what we are doing and that's it. I also have a problem with a client who has no good reason for NOT following my advice; that may be a client that I will dump because I am their consultant and if they don't take my advice here, they may not be a good client in the long run. The problem is they think they know better than me, and that's a real problem if I can't get them over that hump. I don't have any desire to be arguing with them in the future. Now, there are lots of things that I would PREFER, but sometimes the clients actually do have a reasonable reason for what they want (for example, we have few plans that have loans, but the ones that do had "acceptable" - to me - reasons for why we needed to add that provision and do loan documentation, so not the same problem as in this example).
FWIW.
