When you are dining with others, do not stretch your arms across meals to reach for a bowl, spoon or to scoop food from a dish. Courtesy demands that you ask someone closest to you to get that thing you are seeking to you.
In a situation where the bowl is about 1 meter or 3 feet away from you, you should ask the person nearby or closest to you to pass the message to the next person and so on and forth, till it gets to you. Better still, if there is a waiter around, you should lift your hands and try to get their attention for help.
Never find yourself overreaching for something when you are at table with others. Correct?
