Consider however that she wasn’t served this coffee in a store, but in a car. The possibility of spilling the drink is significantly more likely, especially since she wasn’t given a lid. This isn’t the woman’s fault at all, it was a horrible accident just waiting to happen. It’s like if a roller rink covered the floor in grease and periodically had spike pits.
I did a bunch of chemistry lab classes in college, I think I had one each year actually. We regularly heated liquids and worked with concentrated acids. If we had spilled a liquid this hot on ourselves in a similar volume, we would have seen similar burns. It would take longer than 2 seconds to rip off a glove (which is probably fused to your skin very quickly anyway) or disrobe our labcoats. The coffee being spilled on us like this would have given us incredibly severe burns too, and that’s with PPE and emergency safety equipment right there. It would take far, far longer to get to one one of the showers and activate it even.
And this is in a controlled lab environment! There was no heightened risk of spills because of being in a moving vehicle nor having an open cup.
