A diabetic woman walks into a café and orders a cup of coffee. The barista accidentally adds sugar. The woman drinks roughly half the cup, her blood sugar spikes and she ultimately ends up in the hospital after going into diabetic shock.  Now she’s suing the café for negligence.

She and her lawyer claim that the woman ordered artificial sweetener, not sugar. They say the café is to blame because the barista was allowed to add sugar beyond the woman’s presence. The café maintains that the woman never asked for artificial sweetener.

So, who’s to blame?
