The Dunkin' Donuts worker, from the United States, shared how much liquid you actually get if you have ice with your soft drink, as Birmingham Live reports.
And he reckons it isn't even worth it.
He decanted the drink from one cup to another without the ice - and said you actually get about half the amount of liquid.
Talk about a waste of money, eh?
One Tik Tok user wrote: "That's why I don't ask for ice, it takes up too much space and it waters the drink down.
"I always ask for no ice and then just add ice when I get home," warned a second.
"Doesn't surprise me," wrote a third.
