morning minyan
There was a fascinating (to me) discussion at breakfast. There is a light breakfast after services every morning -- usually just bagels and bread, cream cheese, and drinks, unless someone sponsors a fancier breakfast. The process of getting the bread/bagels has been a pain for various reasons, and today someone (a regular, not a visitor) proposed a change: getting bagels from a new bakery that is better in quality, cheaper, more conveniently located -- and not under rabbinic supervision. This last point had not even occurred to the person bringing up the subject as something important; when others pointed it out he went on an anti-kashrut rant. ("What could be treif about a bagel?" "Well, this place sells sandwiches, right? So maybe they sliced your bagel with the same knife they just used to slice the ham?" "You're being too picky." And so on.)
Other people pressed that line of argument with him, but I brought up a more fundamental issue. This is a Conservative congregation. That means they, as a congregation, are bound to a certain interpretation of halacha. It doesn't matter if every member of the minyan eats treif at home; the congregational meal must be in accordance with that halacha, both for appearance and to support the needs of any visitor who actually keeps kosher. (I think, but am not sure, that failing to keep a kosher shul kitchen is one of the issues (along with performing an intermarriage, and I'm not sure what else) that can get a Conservative rabbi censured.) So if that halacha says a bakery must be under supervision, you have to follow that. Bottom line: you have to ask the rabbi and follow his ruling.
The person I was arguing with seemed to be of the belief that "kashrut is silly, so we don't need to worry about it". He failed to see the difference between decisions about personal practice and decisions about communal practice. At one point he brought up other Conservative deviations from the Orthodox interpretation of halacha, like allowing women to lead services, but I pointed out that this isn't the same thing at all: the Conservative movement has a process, which they followed, to determine that women can lead services. They didn't just get up one day and say "we don't like that restriction, so we're not doing it". That same process produces an understanding of kashrut, which must be followed in the shul.
The rabbi was not present, by the way. (I would of course have deferred to him if he were.) I didn't mean to be "speaker for the rabbi", and I said a few times that he needs to consult the rabbi about the kashrut rules for the shul. But when exactly did I, a Reform Jew, become a spokesman for Conservative Judaism in a Conservative shul? *boggle*
(I should clarify that I am not trying to malign or question this community as a whole. I assume that most people present agreed with me but just weren't putting it into words.)

bagel sources
I don't think so, though I could be wrong.
We have two kosher bakeries in Squirrel Hill. From what I gather, both of them have trouble actually having an order ready for pick-up, and correct, at the specified time. This is ticking off the people who pick up the baked goods before minyan.
In addition, people have now tasted the superior offerings of the Bagel Factory, and some of them don't want to go back. (I suspect they would object to Lender's for the same reason.) I'm not a conisseur myself; it's all "generic bread stuff" to me.
The person who brought this up had some resistance to the idea of just getting the baked goods the previous day and living with that, but I think enough people said that would be fine that it might happen when (if my prediction is right) the rabbi tells them they can't use Bagel Factory.
By the way, the bagel issue is a simplification; the conversation started with "are you guys willing to skip the bread and cake and just have bagels?" (we all shrugged) and went from there.
