While working in a busy city hospital on very low pay, I had three years of unfettered access to the medical records of everyone in the city. On top of that I could easily have requested the records of any other UK citizen.
And I did read loads and loads of records, and request loads and loads of records from hospitals around the country, but not once was it out of curiosity. Every file I opened was due to a medical requirement, and was part of my job.
And while I speak for myself, I can assure you my colleagues were too busy and too professional to stoop to such disgraceful behaviour.
Be assured, the bored receptionist woudn't have lasted a week before losing her job for unprofessional conduct, in my hospital and any other you care to mention.
