The elder lady turns and squints at Beamer, smiles, motions for you to come closer. With a gentle Irish accent, she croons cheerfully, 

"You're one of those Imperial Fish & Chippers, aren't you? Oh, don't look so surprised. I suppose you'll do, as long as your eyesight's better than mine, missy. At least you're not one of those bothersome Supers..."

As you join your walking partner, the Smiths each take a step forward simultaneously, notice you've made them, and each look in a different direction. One even whistles with forced nonchalance. 

Game on.
