12) When you drink water, you should not drink in the presence of others; rather, turn your face away. When drinking other liquids, you need not turn your face away. (Ed: I have never heard of this one, have you?)
13) Do not stare at someone who is eating or drinking; nor at the portion in front of him, so as not to embarrass him.
14) If one person is serving food or drink to another, and it has a good aroma which creates desire, the server must be allowed - immediately – to taste from it if he so wishes. It can actually be harmful to a person to see desirable food and not be able to partake of it!
15) Do not serve food to a Jew (i.e. bread) unless you know that he will perform the ritual hand-washing and recite the bracha. (Footnote 5: This is a very difficult issue which can arise in dealing with business associates or with non-religious family members. The matter, when necessary, should be discussed with a competent halachic authority. See Minchas Shlomo by Rav Shlomo Zalman Auerbach zt”l, chap. 35.)
16) (Ed: Here’s an interesting one): A woman whose husband is not present should not drink wine or other intoxicating drinks. If she is away from home, even if her husband is with her, she should not drink wine. If she is accustomed to drink wine in her husband’s presence, she may drink a little, even in his absence.
17) A guest may not take from the food served them and give it to the son or daughter of the host (i.e. without permission). The reason is that the host may be short on food and will be embarrassed if the guests do not have enough for themselves. If there is abundant food on the table, it is permissible.
18) Similarly, when entering someone’s home, one should not say, “Can I have something to eat?” Rather, one should always wait until food is offered. Even if the host invites you to eat with him, it is forbidden to partake of the meal if it appears that there is not sufficient food for the hosts! This borders on robbery, say the Sages, and is counted among the sins for which repentance is difficult… (Footnote 4: …because there is no simple way to measure the exact amount involved.)
