The staff completely ruined my sister's gender ultrasound. It was to be a gender reveal baby shower, and the nurse (who wasn't aware that we were even going to try to find out gender yet, as she wasn't even 17 weeks, and the appointment wasn't to fund out) didn't bother asking if we wanted to know, just said, "oh by the way, it's a boy, if you wanted to know." She was very closed mouthed and rude in general.
