Estate agent rude to other viewers and rushed them around

Had a weird experience yesterday. We promptly showed up to 12:30 viewing just as another couple was showing up. I didn't hear when their viewing was, but she asked us when ours was and it was 12:30. She begrudgingly let us all in (I had a toddler, so didn't fancy standing outside in the cold). I know estate agents like to give an illusion of a property being popular by having back to back or overlapping viewings. The neighbour was also selling and had a ton of interest since it was 200k cheaper, but we really liked the look of this one even at the additional cost.

I am not sure if the other couple was very late, but the estate agent was rude to them the entire time. Like a drawer one of them opened got stuck and she commented how she'd need to fix the drawer they broke now (they didn't pull that hard, I think it was just a bad drawer). They wanted to see the garage and she told them that they needed to hurry since more people were coming (it had been about 10 minutes since we all arrived), and when they turned on the water to check the water pressure she rushed in and asked what they were doing as if they were doing something wrong.

For whatever reason she was perfectly fine with us, I was just surprised to see her treat them that way and I did think it was the estate agent's fault if they had back to back bookings close together. I didn't mind them being there. Is it just so easy now to sell a home that estate agents think they can be rude to potential buyers? Anyone else have experience with a rude EA while viewing? Did it have any impact on your interest?
