Supermarket Showdown: Is This Common Habit Rude?

A couple's disagreement over a common supermarket practice has sparked a public debate. The question: is it wrong to pack your shopping bags at the checkout? Dougie's girlfriend, Teresa, argues that packing at the checkout counter is inconsiderate. She says it holds up the line for other customers waiting to pay. Dougie disagrees. He insists that the packing shelves located further away are meant for this purpose. He believes using them is the correct system and avoids congestion. The couple has submitted their dispute to a public forum, asking readers to decide who is right.
