Jacqui and I have the opposite problem - a checkout clerk with verbal diarrhea. She admires every item (this is a grocery store!)and asks how the customer plans to cook, use or save it. Thirty recipes later I am ready to kill her or simply shout "Shut the F*&*&$%@!^&*(K up and check her out!"
She always has the shortest line because everyone moves to another line.
Infuriating.
