Make the a-ok sign with both your left hand and your right. The left hand makes a lower case b, which means the bread plate is to the left. The right hand makes a lower case d, which tells you the drink is on the right. Also helpful when in a banquet setting, with 12 people jammed around a table meant for 10, and you don’t know which glass is yours.
i am more interested in them learning the order of forks knives spoons! they will dump them all on one side. obviously we don’t entertain much!
