I remember when I was visibly pregnant with DS and looking through the baby section at Target or Myer or something like that I was approached by a budget photography studio representative. They were having an instore promotion, I think, and the woman just wouldn't leave me alone! I told her I wasn't interested and she just kept trying to convince me that I'd love a keepsake when my baby was born and pestering me for details. I finally just told her to shove off (I literally said 'shove off' because I am cool like that) and waddled away to complain at the service desk. Pushy nutter.
Actually, today I was shopping and DS had just bolted out of my grasp (he's slippery and fast!), and as I was racing after a hyperactive toddler, someone actually thought I was in a position to pause for some idle advertising. Like, "Excuse me, miss! literally shove a piece of paper in my face kind" of purchase.
