Why do people act so weird?

So I had to go to the pharmacy the other day unfortunately to get the morning after pill.
I used Protection but it wasn't rolled on properly so he wasn't sure if all the contents was on the wrap.

As a mature and responsible adult I went to get the pill to prevent pregnancy.

Anyways a woman I saw on a dog walk came in, I was filling out the form and the pharmacy was asking me to explain what had happened.

They don't usually provide side rooms for this but I was honest.
"we used a Condom but when he was taking it off he wasn't sure all the Contents was inside as it wasn't all the way up his shaft".

She had to hear this due to the way the pharmacy is set up.

The Asian assistant behind the counter looked like she was judging me too. But I didn't care, I paid, I took the item and left.

I've since seen this woman on my walk with my dog and she hasn't bothered to say "hello" she just stares at me...

Wtf!
