Worst pregnancy scan experience!

I had the worst and rude sonographer... she made a moment that was supposed to be joyful for me to be sad... I was looking forward to this scan for weeks, she ruined the experience for me. she kept speaking to me in a very condescending way... she was supposed to tell me what to do like “pull down your pants down a little bit etc”, but she didn’t, when I asked she said “is this your first baby? You should know what to do”... mind you, last time I was pregnant was over 2 years ago. When I asked any question regarding the scan like where my placenta was, she said “I’m busy trying to do this”... she just kept talking over me to the other lady who was taking notes. She didn’t even tell me what she was seeing on the screen, I just managed to know what the heartbeat was because she told the woman. I was so close to just getting up and leaving, that was how bad she made things for me. I understand that we all have bad days, but she was just awful. After the scan, I sat down and actually cried!
