@daas yochid-
That’s the most common way to reply to someone on the internet.
Thank you.
Also, I’m no posek, but the people who work for the hashgachas are.
As I mentioned, they do feel that they have something to rely on. But bear two things in mind; if a restaurant can’t get a certain hashgocha because of a particular issue, they can keep on searching until they find one which will go along with it, and the Rav Hamachshir is not necessarily my posek or yours. It’s important to be educated about the various issues in kashrus so that we can know what to ask our own poskim.
