PolitiFact investigated a viral claim suggesting that all Starbucks cup sizes hold the same amount of liquid, indicating a potential scam.

The results confirmed that the tall, grande, and venti cups indeed hold different amounts: 12, 16, and 20 ounces respectively, consistent with Starbucks' official size guide. The viral video's implication was thus proven false, categorized under misinformation.
