Wrong impression: any NP complete problem has no finite worst case bound for any heuristic

In network and graph class, we learn that there is no finite worst case bound for TSP. But I thought there is no finite worst case bound for any NP complete problem. Because of this wrong understanding, I argued with a speaker during Informs about his speech about bound of one multi-echolen problem. Of course, he cannot agree on my wrong opinion.

I realize this understand is wrong until today when I happen to read the bounds on Bin-Packing problem.
