I'm the Customer - please guide me and stop asking me to drive!!

This past week I have had a number of lousy customer service experiences where someone who was supposed to be in "service" dropped the ball.
I got my vehicle re-registered and the guy didn't ask me to review what information they had on file. It occurred to me last night at 3:30am that they might duplicate my old address so I called today. Yes, they have old information. The guy on the other end of the phone said, well why didn't you ask to review it?! If you were signing the papers shouldn't you have asked about our computer system?! I said I am the customer, I don't know what the steps are so it never occurred to me.
I had to get new security keys for my condo and when I went to pick up the new ones I dropped off the old ones to the lady at the counter. As it turns out, the old ones work this week and the new ones start next week. When I said I was locked out and returned to their office, they said, Well why did you give us the old ones?! The new ones don't work until next week. I said I am the customer, I don't know what the steps are and no one told me. I thought I was being polite and helpful with the exchange.

Please, please, please remember that your job in servicing clients or dealing with customers (whether its a burger place or a professional services firm) is to guide and lead the client. As the client, I don't know what the process is. I deal with it once a year or maybe monthly but it is NOT my business. I am expecting you to tell me the next step. I am expecting to be guiding along - maybe even with a smile!
Great service is literally and figuratively taking the customer by the hand and telling them what steps you are about to take, why, and then guiding them through each one, answering questions as you go. It is really simple, yet soooooo difficult for many.
Help me be a better client and follower by making leadership and guidance part of your service plan.
