To hello:I might be assuming to much doubt but I am not sure if they fully keep knives clean. I actually have seen counter people in Kosher and non Kosher stores alike using knives and utensils without fully rinsing it off. Strict halacha according to what you say yes you are right.But i just dont trust them to fully clean the knives.Even in frum takeout stores kashrus agencies cannot vouch for things being fully parve and advise to assume everything is fleishig or flieshig keilim.Once again I trust your Halachic knowledge of this issue but this might not be such a black and white issue. So I will not err judgement I will also ask the opinion of a Rav that I know that is a consultant for various local and major kashrus organizations. It could be you are totally right and my concerns are not justified.(will not be back tonight though sorry)When i get back the answer I will post unless someone else does. be well
