I think the cruise line did / does want your feedback, but whomever decided to request it didn't know that particular cruise's demographics.
Here's something similar; not really, but a comparison:
I frequent my local McDonalds in Florida at breakfast maybe 3 times a week (Egg McMuffin, Sausage McMuffin or Hotcakes and a potato and drink). The demographics of the eat-in clientele is probably 80% in the 65+ age group. Starting this week all eat-in customers can only order from one of the two self service kiosks. Counter orders are not being taken. I know how to use the kiosk, but certain variations from what's listed aren't unavailable or are difficult to locate. English muffin well-done (because their toasting device only warms the muffins); light ice in a soft drink; etc. When I stopped in and was refused counter service several other customers were heard complaining about the kiosks. So, I walked out and went across the street to Wendy's where the breakfast sandwich was as good and the "meal" cost 2 dollars less. This, too, is an example of how the management of a business (this particular McDonalds) doesn't understand its clientele.
