The 12-seconds-long clip, which has gone viral online, features what appears to be a woman and a man snuggled up on a sofa.
Other guests are visible in the background.
But the innocent scene isn’t quite so; as the camera zooms in, it becomes apparent that the couple are engaging in something saucier than an afternoon coffee.
A hand can be seen furiously moving underneath a jacket in an up-and-down motion.
The couple’s faces are not shown.
The incident took place in Quilmes, Argentina, and has caused a stir online with close to 700,000 views and 69,900 likes so far.
It is unclear when it took place but the TikTok was shared three days ago (@pablorereok ).
Social media users have come out in droves to comment on the bizarre situation.
“She doesn’t want half and half, she wants the real cream,” wrote one user.
Another person added: “Noooooo,” followed by various emojis.
“He is preparing the coffee with milk,” joked someone else.
“Naaa, I would have gone to warn them and have them removed. Let them go to a square if they need it so much,” added another user.
“Agh, trauma,” said another user.
“She wanted coffee with milk, so she’s ordering it,” said another user.
