In a way I do agree but I seriously doubt I could recall the look and taste of a burger from 2 yrs ago let alone 20 or more but then I don’t recall ever having a Big Shef anyway so to me it would be just a $1.50 double cheese hamburger. Perhaps what Hardees means by "return" is the return of THEIR version of the burger not the one from a long defunct chain. Their version is most likely what the majority of people know.
As far as the picture not matching the product, it IS wrong but it’s not limited to your Big Shef. The recent Monster burger I had didn’t look like the advertisment either but of course it was real not made in a studio.
