Is there ever an instance you would NOT accept getting shit-tested by a woman?

I went to a supermarket and asked one of the cashiers, "Hey, can you tell me where the condoms are?"

She looks at me and says, "A young kid like you. What do you need condoms for?"

I chuckled and responded with, "Oh dear, if you only knew. So, where are they?"

She pointed me in the right direction.

Still, I thought it was highly inappropriate for her to shit test a customer asking her a simple question. :-/

Like the title, is there ever an instance you would NOT accept a shit-test from a woman? How would you handle such a situation?
