The problem wasn't that reservations still allowed you to order them. The problem was that the meals were eliminated in the first place.
One of the excuses for elimating the meals was that they couldn't guarantee to get them right
Wrong. For
several years after all domestic coach meals were eliminated, we were still getting questions from people
in coach about where were their special meals--especially kosher meals. When they called reservations to book their flights, they were told that yes they could order special meals. Reservations never seemed to understand that there is a difference between domestic and international. I once tested it myself, by calling reservations about booking a JFK-LAX transcon. I was told that yes I could order a kosher meal in coach. This was after we started Food for Sale in coach. As someone who spent a number of years in Information Technology, I find it appalling that the company cared so little about the issue that they didn't even bother to program the computer to prevent the special meals choices from even appearing on the screen when booking a domestic flight. Either that or the people in reservations were lying to the customer rather than explain to them that meals were not offered in coach at all--other than food for sale.
Yes, you are correct that we never seem to leave the gate without enough fuel, but then you have someone in authority (the pilot) who can delay the flight if the fuel is not delivered to the a/c. Neither the pilots nor the company care whether or not the meals are delivered to the a/c, or that the ones delivered are the correct ones. (Well, the pilots don't care unless it is THEIR meal that has not been delivered.

)
More than once, I have left the gate for short flights (say, DFW-AUS) with the catering from the inbound leg because there was enough ice unmelted to do a sorta-kinda beverage service. The fact that we had more tonic water than Diet Coke didn't bother the cockpit, or anyone in management, in the least. The important thing is that we pushed on time.
P.S. Special meals will not be offered. The deal is that those who are booked in F/C can reserve one of the offered entree choices in advance (think some alleged chicken dish or pasta). There are LOT of things this airline
should be doing, including offering special meals--especially on flights over 2 hours. But then, after 5,000 years of fighting among those Semitic first cousins, there
should be peace in the Middle East.
