My mother does eat it by the spoon! I could take it our leave it but mostly leave it because it adds too many unnecessary calories. I can say from our experience, having a DH and kids who can't stand the stuff, the paninis and wraps on the Magic had mayo as did many of the sandwiches including the steak sandwich from room service. We always ordered from room service requesting many times no mayo and were lucky to be mostly successful. At Goofy's we weren't so successful. All sandwiches were premade with mayo and it would be at least a 30 minute wait for one without. Seemed so stupid to me, it would be much easier to allow everyone to choose their condiments like they do for burgers and hot dogs. We never bothered asking at Flo's after our experience at Goofy's.
You can't even get a fast food or restaurant burger without mayo automatically on it these days.
