It honestly pissed me off as a barista. In a coffee shop you wouldn't be able to make espresso using water instead of tabasco because you wouldn't be able to switch the water source -a coffee stand you could, but you would need a five gallon bucket of tabasco -which to be fair, Claire likely would have ordered/brought in; quality ROI with the gold nugs.

In the parameters of the story above, what Claire would really be doing is substituting steamed milk for steamed tabasco, and then dumping the two shots of espresso in the steamed tabasco.

The hell themed latte art would then additionally be a pinkish red color, which honestly itself would be a nicer touch than white latte art on what otherwise would be an indistinguishable cup of coffee, if it was being made with tabasco substituted for water rather than tabasco substituted for milk.

And again: you'd actually be able to get a way hotter cup of coffee substituting the milk because our steam wands get absolutely insanely hot -hotter than even the 200 degrees that our machines pour espresso at.
