Not once has he asked the baal tefila to put on a hat.
He knows his customers. Why should he chase some away by asking them to put on a hat?
Then I came to realize that THOSE were the clothes that, for them, were their good, SPECIAL Shabbat clothes (as opposed to the navy blue work shirts and pants most guys wore during the week. So, my point is, it is a matter of intention, of kavana, what makes you dressed appropriately, dressed Jewishly. On kibbutz, the clothes I described, along with a nice bright, clean kippah seruga (as opposed to the ones that get dirty looking from working in them all week) is JUST AS Shabbas’dik as a gold striped kapota and streimel for a Yerushalmi, or an 800 dollar suit and a new Borsalino for someone in Flatbush.
Really? So if they run around in their bathing suit all week, but “l’kovod Shabbos” they put on a Gucci T-Shirt and shorts, its just as good as a suit and tie and black hat, since it is the “intention” that counts?
