Btw that $40-$100 cytology exam test that they charge you for at the vet for an ear infection is literally just them looking through a microscrope and identifying the shape. Meaning, me as a first year biology student could have done that for free.
As someone who works in a vet office, it’s also for labor costs of taking the time from another appointment. That’s being said, I’ve given so many for free bc that’s the stupidest fkn reason.
