On the other hand, I worked for a technical writing firm in Holon and was assured during the interview that the lunchroom was kosher. However, one day we all had to work very late and, per Israeli law, they served us dinner. I noticed that the dairy dinner seemed to be served on the same plates and using the same silverware as for the meat lunches. I think that giving kashruth certification in such a case is dangerous. It seems to me that that would imply that the rabbanite is condoning such behavior.
Some standard is enforced.
As I've said previously, I don't want to be fooled into eating something that MAY BE kosher, where the kashruth is kvetched by using leniencies accepted only by a small minority, as the standard. The best way for me to be responsible for my fellow Jew is by setting an example, not by contorting the system to make what he chooses to do acceptable.
