Recibo de Ventas

Note: The United States does not have an official language. Many Americans don't seem to know this.

Last night I went grocery shopping at my local Hispanic grocery, where I have started to shop more and more, since I discovered that they carry fresh milk, which the Asian groceries don't.
It was cold--near 0 degrees--so I wore my hat with ears, which I didn't bother to take off when I checked out.

Usually the Spanish-speaking cashiers switch to English when they serve me, but I guess this woman couldn't tell, what with me so bundled up (and being half Italian, I am not so far removed anyway), and she greeted me with her usual "Hola!"
I replied "Hola," but she sussed me out, (even one word gives away an accent), and when I paid she said "Thank you."
Still, I was kind of pleased to be temporarily Spanish speaking. Which I am sorry to say I am not, though I have picked up lots of bits and pieces of the language.

When I got home I noticed for the first time that the sales receipt is entirely in Spanish.
Here's what I bought, in both languages:
