gopher shopping
When a completely inept person, sends an equally inept person (or gopher), to do their own shopping. Often, the gopher can be observed standing in the middle of the store, yapping on a cell phone with the person who subsequently sent them. Screaming out a variety of sizes, colours, and prices.
"That customer doesn't seem to know what she wants."
"Of course she doesn't. She's gopher shopping."
"Of course she doesn't. She's gopher shopping."
