"We gotta control this guy 'cause he's a sizable guy. and it looks like he's probably on something".
Mr Floyd was later arrested outside where Chauvin pinned his knee on his neck for what prosecutors said was nine minutes and 29 seconds, as a handcuffed Mr Floyd lay face-down on the pavement.
Chauvin, who was then a Minneapolis police officer, was responding to a witness who confronted him about not getting up and letting Floyd breathe; he also told the witness, who said he didn't respect what Chauvin had done, "That's one person's opinion".
Mr Chauvin, 45, is charged with murder and manslaughter for his role in Mr Floyd's 25 May, 2020 death, which was captured on video and sparked anti-racism protests around the world.
Genevieve Hansen, an off-duty firefighter and paramedic who was near the scene of the arrest, can be heard on the video screaming at the police to check Floyd's pulse.
An employee at the Minneapolis corner store who suspected Floyd gave him a counterfeit $20 bill last May testified in court Wednesday that he felt "disbelief and guilt" knowing that their interaction led to Floyd's death under Chauvin's knee.
The third day of Chauvin's trial featured testimony from several bystanders who interacted with Floyd as well as graphic excerpts of police body camera footage showing his arrest and final moments.
"Waking up, the first thing I hear is Mr. Floyd saying, 'Mom, they are killing me in the street", he said.More news: GOP delegation demands answers amid escalating Biden border crisis
In opening statements on Monday, Prosecutor Jerry Blackwell told the jury that Mr Chauvin had "betrayed his badge" by kneeling on Mr Floyd's neck, and using "excessive and unreasonable force" to detain him.
Mr Martin described knowing the bill was fake by its colour and texture, but added that Mr Floyd "didn't seem to know it was a fake note".
Martin said that when Floyd was inside the store buying cigarettes, he spoke so slowly "it would appear that he was high".
Mr Martin said he told the store manager about the fake bill, however, and he was told to go outside and tell Mr Floyd to return to the store.
"I'm claustrophobic, man", Floyd says repeatedly.
Christopher Belfrey, who came to Cup Foods to pick up food, testified that he saw officers walk up to Floyd's vehicle and point a gun into the window.
"I just didn't want to have to show it (the video) to anyone", he said.

"Mr. Morries Lester Hall, through undersigned counsel, hereby provides notice to all parties in this matter that if called to testify he will invoke his fifth amendment privilege against self-incrimination", said a notice filed by Assistant Public Defender Adrienne Cousins.
"I should have called 911 immediately but I didn't and when things calmed down I realized that I wanted them to know what was going on".
Witness Donald Williams says he called 911 after watching Chauvin shove his knee into Floyd's neck because he believed he had witnessed a murder.
In one of the more tense exchanges, Nelson asked Hansen if she was angry and upset at the scene. "I was desperate to give help".
Nelson also made a point of questioning Williams, a former wrestler who said he was trained in mixed martial arts, about his testimony regarding choke holds.
On Wednesday, she was on the stand for only a few minutes.
He also tried to get her to admit that if she were to try to put out a fire with "an angry crowd" around her, she may become distracted.
After dismissing the jury for the day, Judge Peter Cahill admonished Hansen, telling her to answer questions and stop arguing.More news: Florida Rep. Matt Gaetz claims sex trafficking investigation is extortion attempt
