Starbucks' Olive Oil-Infused Coffee Sparks Controversy Among Customers.

Starbucks customers have reported experiencing stomach issues after trying the coffee chain's new olive oil-infused drinks, which debuted in limited markets in February. Some have claimed that the drinks have a laxative effect, possibly due to the combination of oil and coffee's stimulant effect on the digestive system. While some reviews have been positive, others have warned of stomach-churning experiences. Starbucks has not yet commented on the complaints.
