Baby Shopping

I stopped at Tesco, today, on the way home. When I was at the checkout, I noticed that the couple in front of me had a young baby with them. No, this is not about shopping for babies in supermarkets. That would be cool, but this is not about that. It's about going shopping with a baby. The man was holding the tiny infant and swaying back and forth. That in itself was a bit too metrosexual for me. The woman was packing the groceries and dealing with the cashier. Observing this scene, I was struck by a fundamental question. Why the heck would you bring a baby to a supermarket? As there were two of these people, wouldn't it have been better for one to stay home, with baby, while the other did the shopping, unencumbered?
If it was a single parent, I could understand a little, bringing the baby. Although, even as a single, one could take advantage of Tesco's online shopping, order the groceries, and have them delivered. But as a couple, I see no advantages whatsoever. Not to mention that I, as a fellow shopper, didn't enjoy seeing the baby, nor the man swaying with it. His swaying was giving me vertigo. John Wayne wouldn't have swayed. I think it was Paula Cole who said, "where have all the cowboys gone?" Well, they ain't in the supermarket, pilgrim.
