An automatic soap dispenser provoked a heated debate on Twitter after a Facebook employee documented that the dispenser does not respond to dark-skinned people.

The video, published by Chukwuemeka Afigbo, shows a man with a fair complexion holding out his hand and the dispenser releasing soap. A man with darker skin then put his hand under the device but this time the soap does not come out. The man goes on and takes out a white paper towel and puts it on his hand, and the soap is released on the paper towel.

The video triggered a debate on Twitter, with people discussing whether it is a premeditated racism or a technical malfunction of the device.
