I don’t put ice in any drink at home, except rare occassion iced tea if I just made it and it has not had time to chill. In a restaurant I ice up iced tea, sometimes even add water if it is too strong, I like it very weak. In a restaurant I woud ice lemonaide also. That’s it. I don’t put ice in soda/pop. I prefer to not have any in my water, unless the water isn’t cold.
Lemonaide is different than orange juice, it is made of mostly water to begin with,
My husband also does not use ice, but he adds a little water to MInute Maid orange juice, but not fresh squeezed.
Ice does dilute the drink, it has much less to do with keeping it cold for me. All that ice is a very American thing from what I can tell. I guess some other countries do it too.
