Of all the items to be forgotten in a restaurant food order, it is the "easy addition" that is most likely to fall between the cracks. If you say "...oh, and a lemonade" at the end of an order, it is less likely to be remembered, leaving you parched at the table.
I've found adding an unnecessary embellishment such as a squeeze of lime or "topped up with a dash of soda" makes the request more unusual, and therefore more likely to be remembered.
So this idea is more of a "let's all", but the concept is simply to ask for the lemonade glass to be turned three times anticlockwise due to a superstition or deeply-held belief.
You're likely some wag will turn your glass three times in a clockwise direction to "fool you" into drinking the opposite of what you ordered.
