I've never seen a Waffle House that was posted. About the only restaurant that I've seen posted was Arby's, and of course there are others that we cant carry into because they serve alcohol (NC law).
You can ask just any customer service rep for just about any company and they'll tell you that CC isnt allowed, just because its a "safe" answer.
I can remember when a Lowe's or Home Depot store put the no carry signs up by mistake, lots of folks emailed, most got the same reply. Someone got ahold of one guy pretty high on the tierpole in that area, and he found out that the no carry signs were put up by mistake. They got new sign kits, scraped the old signs off, and put the no carry signs up because they were included.
In short, there was one guy that knew the signs weren't supposed to be there, and a dozen or so other folks that said "no weapons allowed."
If I dont see a sign on my way in, I'm going to assume its okay and CC. I'm not about to ask if its allowed or not, because I know the answer I'm gonna get. IMO that kinda like asking a LEO if he'd give you a ticket for going 8mph over the speed limit. Of course he's going to say yes, but in my county, they cant write you up unless you're doing 9mph over (traffic court got too crowded).
We have Awful Houses here, but I've not been to one yet. Am I missing anything?
better burger than McD's for the most part (and sometimes the food is faster), otherwise it varies by location. Sometime you can get a good meal, other times they crap on the plate and serve it. Most of the time its somewhere in the middle.
