The son of a Rhode Island restaurant owner was fired from his bartending job after putting the word "fatty" on a customer's receipt.

The customer, Dillon Arnold, told local news station NBC 10/WJAR-TV that his receipt from All Stars Bar & Grill included the word "fatty" in a spot for his name, which Arnold shared on social media. The photo of the receipt went viral and generated a lot of outrage before it was apparently removed. Arnold told NBC 10/WJAR-TV that the body-shaming incident was very hurtful to him.

"I was signing my slip," Arnold said. "I didn't really pay attention to it yet, and then I just happened to read it, and I saw it in the corner, and I was like, 'Wow.' And my heart just dropped."

Restaurant owner Tony Ambrosio offered Arnold a gift card as an apology, but Arnold said it would be too "embarrassing" to return.

Ambrosio's son, Antonio Ambrosio Jr., has since owned up to being the employee who put the note on the receipt. He apologized on Facebook for his behavior and revealed that his father "rightly" fired him from his job at the bar:

"What I did was immature, and I acted without thinking about the consequences," the younger Ambrosio wrote to Arnold. "I acted in a way that was rude, childish, and totally inappropriate. Due to my actions, I was terminated, rightly so. I would like you to know that I was not raised that way. I hope you don't judge All Stars or its employees based solely on my actions. Again, I want to apologize for my actions and hope you can accept my apology. Thank you."

The elder Ambrosio said in a statement to NBC 10/WJAR-TV that he did not raise his family to treat others this way and that he wants to hold his offspring and workers accountable for what they do.

Arnold is still smarting from the incident: He told local news station WPRI 12 that the situation "kind of ruined my self-esteem a little."
