TWO TV stars caused mischief at a local Costa drive-thru for their hit primetime TV show Ant and Dec's Saturday Night takeaway.

On Saturday night (March 13) Ant and Dec were spotted pretending to be employees in the Costa drive-thru at the Cippenham retail park in Slough.

The comedy sketch saw the Saturday Night Takeaway pair mess around with customers as they drove up to place their coffee orders.

Ant and Dec captured hilarious moments at the Costa drive-thru as customers were asked to wait and carry out facial recognition.

Ant would take customers orders by saying: "Welcome to the world's first automated drive-thru. How are you today? Are you ready for a coffee? Now for facial recognition in 3, 2, 1...'60 second countdown begins'".

The clip on the ITV show saw a woman looking fed up as she was forced to wait ages to grab a coffee.

When a different customer pulled up, Ant asked them to hold their face for 7 seconds for the facial recognition before playing annoying hold music.

The customer was then asked to smile for the camera instead and when that wasn't successful, the pair messaged around with him again asking him to pull a surprised face.

The TV show aired some hilarious moments which you can watch on catch up on the ITV hub.
