I suggest that you request that the management put up a sign in the Monsey Starbucks which lists what items are Kosher and who issues the certification. I have seen this done in other places in Manhattan and Los Angeles. Years ago Baskin Robbins used to post that their Rocky Road ice cream was not kosher but that the other flavors had the hashgocho of_____. Of course this is a small step and does nothing for the tznius violation. It is also sad that the very excellent kosher cafes in the area that are owned by frum people are losing the business-especially when in harsh economic times-every customer counts.
I do empathize with Devora’s feelings and she must be a special person to feel for another yid. Most people really do not care at all if they see a frum person doing something improper, they do not feel anything on the inside. We are responsible for each other and our collective merits will bring the geula. The ones who still have sensitivity are also going to be sensitive and uplifted when they see the loads of kiddush Hashem that goes on among Yidden everywhere.
