It takes all kinds.
Exactly.
The way any individual Jews observe kashruth tends to be highly idiosyncratic and based on complex factors that include what sort of Judaism they practice (Orthodox, Reform, Conservative, Reconstructionist, Renewal, Hasidic, Secular Humanist...), their heritage (Ashkenazi, Sephardi, Mizrahi, Beta Israel...), the teachings and judgments of their rabbi, their level of commitment and other personal inclinations.
Just what is kosher, or kosher enough, is subject to great debate within the Jewish community (Google on "glatt" and "Hebrew National," for a sample). So on one end of the spectrum, you have Jews who worry that transparent, microscopic crustaceans in New York City water render it treif, and at the other, Jews who refuse to drink a milkshake with their cheeseburger.
(BTW, JiLS, cheese is perfectly kosher, even when made with rennet -- if the rennet came from a kosher animal and the cheesemaker is Jewish,
at least according to some rabbis.)
The rules of kashruth are extremely complicated and different authorities and individuals interpret them differently. (That's what you get when you have a religion with no central authority and at least 3,000 years of arguing behind it.)
Here's one example of how complex things can get, and
this thread offers a lighter take.
As for the friend who's helping to entertain the British visitor, he is modern Orthodox, we've been acquainted for more than 20 years, and while I don't know where he stands on glatt or cholov yisroel or the kosherness of raspberries, nor whether he worries about
mar'it ayin, I know he won't eat food cooked in a nonkosher kitchen.
However, he, like the rest of us, wants to show our guest a good time in Chicago.
