I never judged, but I did notice that if people were buying something they thought was embarrassing they'd also buy some other item. No one bought just a pregnancy test, only a box of condoms, a single tub of lube. No there was always some other item, like a candy bar or bag of chips, as if they were worried I was judging them for buying only the "embarrassing" item. I wasn't, I just found the pattern amusing. I know you didn't come to the store for a candy bar and then thought hey I should grab Plan B while I'm here. I don't care, and if the polite fiction helps you get through the day go for it. But it is amusing.
