A McDonald's worker shared a video, proving that every drink is the same size. Now, the Internet's gone mad.

Is he right, though?

A revelation on TikTok

The worker's name is Mykah, and he took his findings to TikTok to announce his shocking claims to the world.

While at the famous fast-food chain, Mykah did an experiment, and his first stop was a small Coca-Cola.

He pours Coke into a small cup, then into the regular size, with the liquid almost reaching the top.

The liquid then goes into a large serving, and again the drink can be seen almost fulfilling the top.

The viral video has over 1.6 million likes and thousands of
comments.

Apparently, size does matter since the video got so much attention, and it's divided the whole TicTok and Twitter communities.

Coworkers to the rescue

A fellow McDonald's employee backed up Mykah and shared a trick to ensure you always get the maximum amount of drink.

He says:

I worked at McDonald's and this is true, always say no ice or ice on the side (in another cup) and only order smalls, NEVER medium.

But many were suspicious:

One Toker wrote:

That's what happens when you fill up each of the cups slightly and then pour more in.

Another one was just as skeptic:

You really think we're gonna believe this.

McDonald's is full of surprises, mostly not pleasant ones. But, every fast-food chain has its share of not quite flattering discoveries. And most involve health code violations, so this whole beverage thing isn't a big deal.

Back in 2017, one McDonald's had 27 health code violations during a routine check-up. It was in Mesquite, and the place got shut down.

Still, it's going to save you a buck if you believe in what you see in the video. We do, and we're not lovin' McDonald's right now.
