jdb – that example makes more sense to me than the OP’s scenario. In your situation, it makes sense to at least ask the sheilah, and I wouldn’t be surprised if there are Rabbanim who would allow it (depending on the specifics of the situation).
But in the OP’s case, I personally found it hard to even see where there is even a sheilah.
I had been thinking of pointing out that the only cases that I would think (IMHO) that it might make sense to even ask a sheilah are: 1. If you are visiting relatives, and/or 2. If you are visiting someone out-of-town where chalav yisrael is not available.
My impression is that in general, there are more likely to be leniencies when it comes to family than when it comes to good friends. Family relations can be much more sticky. I have heard of people being more “meikel” about tznius, for example, when it came to relatives who were visiting.
