A disgruntled woman splashed a piping-hot cup of Joe in the face of another woman after the two got into an argument over a coffee stirrer at a Philadelphia Starbucks, Fox 29 reported.

The incident was caught on surveillance video that shows the two women confronting each other. The argument intensifies and the taller woman appears to take out her cup of coffee and splash it in the face of the other woman. The video cuts to the taller woman hitting the other smaller woman and eventually slamming her on the concrete.

“It was confrontational,” Tony Bennett, a witness told Fox 29. He said the taller woman was bullying the shorter one.

The victim was reportedly sent to the hospital with a number of injuries, including burns to her face.

Authorities are still searching for the aggressor.
