If you stir your iced tea with an iced tea spoon, the spoon stays in the glass while you drink the tea. To do this, trap the spoon against the side of the glass with your index finger, while you wrap your other fingers around the glass.
If there is a lemon wedge with your iced tea, you may squeeze it. A lemon slice is a garnish and it is just there to look pretty. Do not squeeze the lemon slice, nor grind nor pound it into the bottom of your glass with your ice tea spoon (no matter what kind of day you have had so far.) You may put either the wedge or slice in your tea or leave it out on a plate underneath your iced tea, a salad plate or dinner plate.
