South Central Ambulance Service then shared the note to Twitter, pleading with people to be more understanding of emergency services.
"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," they tweeted, adding the hashtag #DontAbuseOurStaff.
The tweet soon sparked a furious response, with people quick to call out the homeowner's "disgusting" behaviour.
Meanwhile others responded to say that they had no problems with emergency staff parking across their driveway — with one person even inviting them in for a cuppa.
"Feel free to park anywhere at mine. I'll even pop the kettle on if you have time," one said.
Another wrote: "You can block my drive any day of the week and any time of day, thank you for the amazing work that you do."
South Central Ambulance Service's governor Barry Lipscomb also responded to the note, tweeting that the views expressed in the note were thankfully in the minority.
"Happily, this sort of mindless carelessness is completely alien to the widely expressed deep appreciation for the skills and caring of our excellent ambulance crews. Only this week, I was grateful to have been treated by them myself - 5 star all round."
