People are shining a spotlight on companies' racial discrimination after Starbucks arrests - here are 6 incidents that show how common the problem actually is

LA Fitness forced two black men to leave a gym in Secaucus, New Jersey, saying that they had not paid to be there. The men — one member and one using a guest pass — said they were repeatedly confronted by employees and police while trying to work out in April, soon after the Starbucks arrests.

LA Fitness blamed the incident on employees' confusion.

"We have spoken to the member to apologize and assure him that he and his guests are welcome in our clubs at all times," the company said in a statement to NBC. "I can confirm that the 3 employees most closely associated with this incident are no longer with the company."

Chikesia Clemons was arrested at a Waffle House in Saraland, Alabama, in April. Cell-phone footage of the arrest, taken by Clemons' friend, shows multiple officers physically wrestling Clemons to the ground, exposing her breasts.

Waffle House said in a statement that while the company was still "obtaining and reviewing information," "the information we have received at this point differs significantly from what has reportedly been attributed to Ms. Clemons."

"After reviewing our security video of the incident and eyewitness accounts, police investigation was appropriate," Waffle House's statement continued.

Neighbors called the police after seeing four people — three of them black — loading their suitcases into their car after a stay at an Airbnb in Rialto, California, in late April. The neighbors suspected the Airbnb guests were burglars.

Police questioned the guests, eventually releasing them without any charges.

"Airbnb's mission is to create a world where anyone can belong anywhere and we have aggressively worked to fight bias and discrimination in society," the company said in a statement to CNN. "We are also reaching out to our partners at the NAACP, National Action Network, Color Of Change, and others to discuss this matter and ensure we are doing all we can to protect our community when they travel."

Mekhi Lee, Dirone Taylor, and Eric Rogers II were shopping at a Nordstrom Rack in Brentwood, Missouri, in early May when they noticed they were being monitored by store employees.

The black teens left the store, only to be approached by police pulling into the parking lot. Police told them that they had received a call accusing three black men of theft. The teens were allowed to leave without charges after an investigation.

Following the incident, Geevy Thomas, president of Nordstrom Rack, met with the teenagers and their families to apologize.

"I feel fortunate to have met these young men and their families. I appreciate the opportunity to listen to their concerns and offer our sincere apologies on behalf of Nordstrom," Thomas said in a statement. "I also want to thank the young men for their poise in dealing with local law enforcement and the police themselves for handling the situation professionally."

On Sunday, Waffle House employees called police on 22-year-old Anthony Wall after he got into an argument with several workers at a Warsaw, North Carolina location. Footage Wall shared on Facebook shows an officer choking him and slamming him to the ground.

"We are looking into the incident that occurred at our Warsaw, NC, restaurant to gather all the facts," Waffle House said in a statement. "Initial reports say the customer became agitated, and the police were called. In an interview with WTVD-TV in Raleigh, NC, Mr. Wall said he took things too far with our employees."
