"i've had the scan here before" cool, then you should know you need a referral

"i didn't need one last time" either you're lying, it got sent through to us in advance and we called you, or someone's fucking breaking protocol. regardless, Not My Problem

"well can you just save me a spot until i get the referral" we can't save shit without making an appointment, which you need a referral for, and you don't have one, so fucking stop

"can you just tranfer me to a radiologist" they're gonna say the exact same thing
