Buying porn
I know a woman who works at a bookstore. She says that guys come in all the time and buy porn, or playboy, or magazines like that, and they do that with their girlfriend next to them. They usually put the magazines at the bottom of a stack of other magazines about computers, or business, or something else. As if no one will notice if they're at the bottom? My friend often holds up the hidden magazines and pretends to search for the bar code and/or price with lots of “it's hard to find the price on these, where is it?” The boyfriend will begin to shift uncomfortably back and forth.
