I was recently phoned by a bank who wanted me to answer a survey about a particular branch that I sometimes use. Since the branch concerned has been designed in a more "modern" format (where it's a challenge to find the counter that you need), I once again put aside my usual aversion to phone surveys and let them have the benefit of my (mainly negative) thoughts.
A little while back I received by mail a survey about the treatment I had received during my recent medical issue. At least the fact that this arrived by mail was less intrusive, but I thought 4 pages of questions a bit excessive, especially as the essence of my answer to virtually all of them would have been along the lines of, "I got the service I paid for and expected, everyone concerned appeared to do their job, and I didn't seem to encounter any real mistakes". I struggle to express this in terms of a rating on a scale of 1 to 5. I suppose, if pressed, I'd characterise the response as being "4 - good".
The upshot was, why bother, and I put the survey aside. I've now received a follow-up letter politely encouraging me to return it. I'm still considering whether or not to do so, but at present it looks as though inertia will prevail!
