S2·E9 The Wild Pitch

As she leaves Sid's store after arranging to hold Nathaniel's birthday party there, Sophie breaks his front window while tossing a ball to Benny; while she is more than willing to pay for the damage, she wishes to go with the lowest bidder ($85 from Simpson's) instead of a repair made by Sid's uncles ($179). When Sid disagrees, an alarming escalation of hostilities occurs, starting with a rabbinical arbitration and deteriorating to legal action that culminates with Sid refusing to serve the boys and cancelling Nathaniel's party.
