Two nurses were spat at by a raging yob who refused to cooperate as they tried to care for him in hospital.
The thug lost the plot when he was asked to wear a mask and answer simple questions about coronavirus symptoms when he was admitted.
The 33-year-old spat a the two women when he was moved to a side room after he kicked off.
The sickening drama unfolded at 9pm at the Royal Alexandria Hospital's accident and emergency department, the Paisley Daily Express reports.
The 40 and 23-year-old medics were following procedures for preventing the spread of the virus when he took offence.
The man also pushed one of the nurses.
A Police Scotland spokeswoman said: "We can confirm officers attended the Royal Alexandra Hospital in Paisley on Monday evening to reports of male causing a disturbance within the Accident and Emergency department.
"Assaults on frontline staff will simply not be tolerated.
"NHS staff working long hours under challenging circumstances deserve to be treated with respect and not fear being targeted in their place of work."
A spokeswoman said a 33-year-old man had been arrested and charged with assault.
