Say this
Fountain cup filled with Unsweet Tea (not Sweet Tea)
Sweet Tea is usually right next to it, with 73g sugar in a 22 oz cup, so check the tap label. The catering gallon of Sweet Tea is the same sweet tea.
Instead of a Sweet Tea, 22 oz (73g sugar)
What's in it
Unsweet Tea, 44 oz (largest size; smaller cups are less)
