Context: I was at the local Mega - Shop - And - Save last week when I realized I 'd been asked to whitewash the fence ... metaphorically speaking . Actually I was at the cheerfully - named ( but badly spelled ) " U Check " stand scanning and bagging my own purchases . If I wanted lighthearted small talk while I checked out , I 'd have to supply that myself as well .
