At a supermarket: The checkout operator (50s?) gives a woman (30s?) a grin after scanning her groceries. She says: "D'you want to know the damage, love?

The other woman laughs: "Hell no! Just tell me when to swipe my card and we'll pretend this never happened!" (4)

Me too. (Small acts of rebellions, just like snowflakes, when grouped together, can make a blizzard of difference.)
