Christopher Cristwell says the way he pokes fun at customers in the song he posted on YouTube are based on his five years of working as a barista at Starbucks in the central valley.
"I'm being incredibly honest about the work experience for a lot of baristas that work for Starbucks," Cristwell said.
So far the song has had more than 100,000 hits on YouTube.
Cristwell says while his bosses praised his creativity he was fired from his job at Starbucks in Chowchilla.
Starbucks released a statement Thursday saying, "The disparaging remarks about our customers and company are unacceptable and out of line with our commitment to our customers and partners."
