The espresso machine is broken again.
"The espresso machine" is a singular noun (it), so we use "is".
My manager and the head baker are arguing loudly.
"My manager and the head baker" forms a compound subject (they), which requires the plural verb "are".
Right now, I am hiding behind a giant pile of coffee beans.
The first-person pronoun "I" always pairs with "am".
