Video shows what the buttons on McDonald’s drink lids are for

McDonald’s lovers had their minds blown after seemingly learning the purpose behind the buttons on the top of drink lids.The plastic buttons – sometimes labelled “Diet”, “Cola”, “Tea”, and “Other” – allow workers to indicate what the customer ordered so that they’re given the correct drink.For example, if someone ordered a Diet Coke at a McDonald’s drive-thru, they’d be handed a drink with the “Diet” button pushed down on the lid, while the other buttons remained unpopped.Source: Michael Mckee, TikTok
