McDonald's Worker Shares Drive-Thru Fact That Many Didn't Know About

In the clip, she revealed there are some technology employees use to help streamline the orders, including a camera that takes a photo of the driver so they know which order belongs to which car.

She said: "The fact that people don't know we can hear your convos even when we aren't speaking to you taking your order.

"And we have a camera at the speaker that takes a picture of you so we know whose order is whose."

The TikTok user added: "Seeing the mugshots of random people makes my day."

And it seems to be something many other people were completely unaware of, with the video racking up more than 857,000 views and 105,000 likes.

One person jokingly commented: "How can you hear our convos when you don't hardly hear the order."

Someone else thought the same thing, writing: "How can you hear my convo when you can't hear me screaming into the mic from 5cm away."

A third added: "My bf always goes HELLO HELLO HELLO?!?!?! If there's no response immediately. And I'm like shhhhh."

In response, @secretfitzz then said: "If you shout hello at us we will purposely make you wait longer and start bitching about you to whoever is on shift w us."

When someone else asked how workers 'still hand out the wrong order', @secretfitzz explained: "Sometimes the bags get mixed up if we're rushing and can't check, or if we ask if their order is right on the screen, they say yes and don't acc check."

Another asked: "If you take a picture why do you have to ask me if that's my order on the screen?"

She replied: "We know that's your order but we have to ask anyway, so if you still pay for the wrong order or your order is wrong it's on you, not us."

Something to look out for next time you roll up for a Big Mac and fries.
