The incense offered in the Temple had 11 ingredients. One was galbanum which has a foul odor. This teaches that even the non observant have to be included in the service of G-d.
If we are more inclusive in the coffee-room, the services will be more inclusive as those not yet observant will feel more welcome.
They will then come to see the beauty of Shabbos and stop texting on Shabbos, and partake of Shabbos related pleasures instead. With greater unity and observance the Temple will be rebuilt.
