A crew of life saving paramedics returned to their ambulance to find an insulting note slapped on the windscreen.
The crude sign aimed at the emergency service workers criticised them for parking their vehicle over the householder's drive.
"Dumbass!" the note, which was covered by plastic to protect it from the elements, exclaimed.
"You are fully blocking my driveway!"
South Central Ambulance Service NHS Foundation Trust said the crew were on a 999 call in Lymington, Hampshire.
The service posted a photo of the note on its Twitter account above a caption defending its paramedics.
"Sadly, Zoe & Chris came back to this in in Lymington, Hampshire, today," the post explained.
"It's not always possible to park without obstructing traffic flow or driveways as parking further away could add minutes to our arrival time that the patient simply doesn't have.
"#DontAbuseOurStaff."
Mark Davis, South Central Ambulance Service governor, expressed his disappointment at the note.
“Disgusting to see, very sad that some people do not appreciate that amazing work our clinicians do every day of the week," he wrote.
The trust, which serves more than seven million people across an area comprising of Hampshire, Berkshire, Buckinghamshire and Oxfordshire has received 800 supportive comments after posting the note.
Ellen Taylor said: “Unbelievable, just hope that person is never the emergency, they might be more understanding and compassionate.
“You all do a great job for which most of us are incapable of doing. Thank you for all you do.”
Dr Sarah Schofield, chair of the West Hampshire Clinical Commissioning group, said: “Ambulance teams and the wider NHS support patients and save lives across Hampshire.
“No NHS staff should suffer any form of abuse, and it is vital that emergency services can access people’s homes as quickly as possible to treat a medical emergency.
“We would like to thank ambulance teams for their continuous hard work and dedication, especially as we head into the busiest time of year.”
