Ever had an obviously inexperienced or nervous tech or nurse

I had to have a testicular ultrasound a few years back and the poor radiology tech was very nervous and/or inexperienced. She must have used an entire bottle of the gel, she kept going back and redoing scans and measurements. She probably apologized 100 times for whatever. Sorry about that, oh my fault, I'm so sorry. It took a very long time, I've had two follow ups since then to monitor my condition and it has never been nearly like that first one.

Anyone else have a similar situation where the nurse or tech was very obviously having a bad day?
