You can tell a lot about a person from what you see in their shopping cart. I always look at what others have in their cart while waiting in line. My mom had a box of food from Instacart delivered to her by accident one day. The driver was gone by the time she answered the door, and there is no way to find out who had actually ordered the food, so she kept it.
In the box was the following: 4 loaves of Milton's bread, several pounds of sliced turkey, several half gallons of Silk Almond Milk, and 2 large watermelons. She determined someone was having a party!.
Have you ever looked at the shopping cart of two college men, stocking their refrigerator? Sugary cereals, chips, dips, puffs, crackers, frozen pizza, ramen, beer and soda, are just some of the more popular items they might have in their cart.
A health food nut is going to have a very different group of items. He or she may have fiber bars, fresh fruit, yogurt, nuts and raisins, fresh vegetables and hummus dip, fat free crackers, bottled water.
The coupon freak is going to have a huge variety of items. He or she will buy anything that she has a coupon for, whether she wants it or not.
Then there's the basic family shopper. Her basket is loaded with just about everything, from orange juice and ice cream, to chicken, beef, pasta and sauce, to soft drinks and chips.
Then there's me. Since I'm shopping for one, I don't usually buy much. (unless I'm at Costco). I will buy 4 apples, a few oranges, a quart of milk, a dozen eggs, a few potatoes, a head of lettuce and some veggies (many of which go bad because there are too many), cottage cheese, sour cream, yogurt and salsa. There's not much incentive to make a nice dinner for one, so I rarely buy meat. Cooking for one is another topic for another day.
In any event, I think you can tell a lot about a person by what's in their cart. How big is their family? Do they have a pet? Do they have children? Do they follow a healthy diet? All this information and more from just a few items in a shopping cart.
