20 week scan was disappointing

I was excited for my 20 week scan today and to see how much my son had grown. Walked in and there was another tech - I guess my normal girl wasn't working today. This girl was dead silent the whole time and only opened her mouth if I asked questions. Even then she was very short. She wouldn't even turn the screen so I could see my child. So I had to strain my neck the whole time, while trying to not sit up too much, just to see a glimpse of the baby. My fiancé was there and asked a question about the placenta and instead of answering the damn question she rudely commented "I'm not even measuring the placenta"... at the end she gave me pictures and to be honest they were shit too. Blurry, can barely tell what it is, and every photo was almost identical. 

I'm just disappointed.. looked forward to this day for a while and I feel like I could have experienced a little more with someone different. Doctor called me later and said my results were almost perfect and he's measuring right on track. So it's not like the tech was trying to keep quiet for health concerns. 

I have to go back for a follow up ultrasound in 4 weeks for another reason, and I'm really hoping that appointment goes better.
