The previous shiur discussed that sorting is only permitted when 3 conditions are present: #1- For immediate consumption. #2- When sorting by hand. #3- When sorting the food from the refuse.
1- Immediate consumption
The Mishna Brura [ 321:45] rules any preparation for the Seuda involving sorting, could only be performed after men have left shul. Sorting prior involves an Issur Deoraisso [Torah Prohibition].
Setting the table • The M”B  rules that dishes are also subject to the restrictions of Borer. Sorting mixed up silverware to set the table could only be achieved prior to the meal.
• If the housewife wishes to set the table before going to shul, she may do so if no sorting is involved. Otherwise, it could only be performed after Shul.
Meeting the family • If the housewife wishes to meet her husband on his way back from shul, preparations involving Borer could be performed only after her return, unless it only takes a short time.
Setting up a kiddush • Often preparation of a kiddush include sorting, therefore the restriction of time applies. I.e. The kiddush may not prepared before Shul. The preparation can only start however time it is required for the kiddush to be ready on time. This Din applies to caterers too.
Lending a dish • If a friend needs a dish that would require you to sort; It is allowed to sort [given all conditions are respected] as it is considered for immediate use. However, if the friend needs it at a later time, it is then forbidden to sort.
Maid • The restrictions of Borer apply to a maid too, as she prepares for Jewish people. So, she is prohibited to sort early despite wanting to finish up and leave.
Similarly, a daughter visiting her parents Shabbos morning is not allowed to prepare the egg salad for the afternoon meal, despite if she cannot come back later. [The above 3 rulings are based on SS”K Vol 1 footnotes 185 & 190 in the name of Rav Shlomo Zalman Auerbach]
There are endless cases, and one must be very careful before ruling whether a certain case is considered prior to a meal or not.
