Cameron Sandé, 23, visited the branch near Gipsyville, Hull, on Friday night and went straight to a table to order from the McDonald’s app.
But a security guard soon approached them to ask them to leave if they were not ordering any food.
During the confrontation, the employee allegedly Bioreports Newsed the table and is said to have called Mr Sandé a “muppet” and a “stupid white boy”, Hull Live reports.
“He Bioreports Newsed the table really hard and was intimidating us. There were only us there and two teenage girls around 15 or 16 years old watching us,” Mr Sandé, of east Hull, said.
“I was fuming. I wasn’t going to let someone intimidate us and speak to us like that so I went to tell the manager.
“I was getting angry, my friends were scared and anxious. He called me a stupid white boy. If it was the other way around I would get done for racism.
“He was being abusive and racist to us. The manager said to him to calm down and told him we were ordering from our phones. He started putting his hands in the air and laughing.
“When I was telling the manager what had happened he was trying to scare me into not telling him. I told the manager about him Bioreports Newsing the table and he denied it. He kept saying, ”shut up, shut up.'”
The manager offered the group some free McFlurries to try and resolve the issue.
But the diner remains upset and intends to take the matter further.
“Security guards in nightclubs aren’t like that but he was in McDonald’s. I was getting angry and told him to ‘f*** off’ and called him a fake cop. I was really intimidated and angry and didn’t want it to kick off,” he added.
“I messaged McDonald’s on Twitter this morning and was going to go to the police but I don’t think they’ll be able to do anything.
“I’m not going back to that McDonald’s again.”
