My grocery store experience at least twice per month:
Checkout Girl (Frowns): "Whus this?"
Me (Internal): " The fuck? You just scanned the gotdamn barcode; can't you read?"
Me (External): "Oh, those are multicolored mini bell peppers!"
Checkout Girl (Curling her lip): "You eat dat?"
Me (Internal): *sighs*
Me (External): "Definitely! They're really good for you; they have more Vitamin C than oranges!"
Checkout Girl: "How you make it?"
Me (always looking for a teachable moment): [Gives her 2 quick recipes]
Checkout Girl: "For real? That sound GOOD!"
Me (Internal/External): [smiling] "Oh, it IS! You definitely should try it! At least you get the employee discount, so it'll be cheap for you!"
Checkout Girl: "Oh I will! You have a GREAT day!"
*smiles all around*
