Machshirin 2:5

Let’s say that there’s a town whose residents include both Jews and non-Jews, and the bathhouse is open on Shabbos. If the majority of residents are non-Jews, one may bathe there immediately after Shabbos; if most are Jews, one must wait long enough for the water to be heated. If they’re 50/50, one must wait long enough for the water to be heated. Rabbi Yehuda says that if there’s a small bathhouse frequented by government officials, then one may use it immediately after Shabbos (on the assumption that the water was heated for their use).

Machshirin 2:6

Let’s say that vegetables picked on Shabbos were being sold in the town. If the majority of residents are non-Jews, one may buy them immediately after Shabbos; if most are Jews, one must wait long enough for the vegetables to be brought from a nearby locale. If they’re 50/50, one must wait long enough for the vegetables to be brought from a nearby locale. If there are government officials there, then one may buy them immediately after Shabbos (on the assumption that the vegetables were picked for their convenience).
