Smoothie King will temporarily close two North Carolina locations after employees wrote racist notes on customer receipts over the weekend, according to the Charlotte News & Observer.

“Today, two instances happened in our Charlotte franchise stores that are totally unacceptable and go against every value that we stand for. Two of our team members wrote inappropriate, racial remarks about our guests,” the company told WBTV Sunday.

Both incidents occurred on Sunday, according to receipts posted by the recipients. One case involved the n-word in place of a customer’s name and the other receipt listed a Korean customer’s name as “Jackie Chan.”

“I was just in this Smoothie King with my kids. Instead of asking for my name. Zack H. thought it would be funny to put ‘Jackie Chan’ as my name. Being Korean, I find this very insulting. But the 3 employees working there at the time couldn’t stop laughing about it,” the customer in the second case wrote in a Facebook post. “I experience racism here and there and usually doesn’t bother me. Today I left this store furious on the inside, trying to not let my young kids know what just happened.”

Smoothie King said both employees have been fired and their respective locations will close while the teams complete additional training to ensure no similar incidents occur.
