creepy

... yes. Yes it can get more creepy.

You gotta watch out for those Starbucks lovers.

Laura Roberts, a 19-year-old customer at Starbucks in London, received a rather flirty (and cheesy) message on her coffee cup from a male barista.

The unidentified employee scratched out the hot coffee warning and left this message: "Careful you're extremely hot" with an arrow and smily face.

Calm down, lover boy!

The thing is Roberts is engaged and her mom has Facebook—both big problems. Her mom posted a photo of the cup on the Sh*t London Facebook page.

The post received tons of backlash and angry comments, but Roberts is choosing to not identify the barista.

"It's my local Starbucks and he's lovely," she told MailOnline. "He always does it."

"That day I sent a picture of the cup to my mum, because she lives quite far away and she put the picture on Facebook."

Moral of the story: Keep mom off Facebook.

Mind your audience, guys.
