Of course the plaintiffs attorney argued coffee should be lower temperature - it literally was their case.
And no, there is no coffee professional (organization, individual, whatever) brewing coffee at 140*F.
Additionally - 140*F water is still going to burn if you spill it all over your clothing. Lastly, the customer removed the lid of the coffee while between her legs, which is how the cup was crushed and coffee ran all over her.
The case was absurd...
