It's not a feeling, it's just how it is and if you've worked with the public enough you'd know it.
I wish signs, bold letters, hand spooning and everything worked for everyone but it doesn't. Retail and food people get it quite quickly that there is no way every single person they encounter pays attention to things, even right in front of them. Heck even when I was in corporate world people can be that way. I was in insurance world my husband in engineering. Oodles of stories to tell and across the nation, and globally (germany, canada, mexico, india, etc) somehow doesn't seem to matter.
Your opinion is Disney isn't doing it well enough, what isn't up for debate is that there will always be people, sometimes a lot, that still don't get it. Even ones who call for improvement to the park reservation system seemed to get that.
