Insignificant bits of frustration.

Tom Asaker had a rant that got me thinking about my law practice. First, Tom's rant:

I know this may sound a little persnickety (to the unenlightened branding guy or gal anyway), but here goes: How come I pay well over $20 for a hair cut and I always leave with little hairs all over my neck and ears. Sure, the service and quality are decent, but come on! The salon should really consider my experience before, during AND after my visit. Right? I guess you should probably wonder as well, what insignificant bits of frustration are you leaving with your customers? Heed Mother Theresa's wisdom: "Be faithful in small things because it is in them that your strength lies."

As a lawyer, I do my best to focus on solving my client's problems, but now I wonder if dealing with the problem is just the "haircut." What can I do to improve the customer/client experience after they visit me? I've been thinking about a few ideas, including sending a follow up thank you note (mailed separately from the invoice) that includes a quick survey -- and perhaps a coupon for a discount on future services like estate planning or something similar. Maybe even start a "birthday club" that gives them a quick 30 minute consultation on their birthday as my "gift" to them. Like I said, I'm just brainstorming here. Anybody out there have better ideas?
