I work as a cashier at a grocery store, I recently transferred to a different location where 90% of the customers are senior citizens. You'd think this would mean more mature customers... No.
At our store we sell bulk items like nuts, candy, rice, etc.. You put it in a little baggy and we weigh it up at the register. The bulk items are really popular but can be really expensive. This leads people to writing false codes or mixing more expensive items in cheaper product and only writing the cheaper code.
I was cashing out an older lady and she was laying everything up but I noticed she had a bulk bag to the left of her purse (I was to the right). I usually wait until I'm about to tell the total to bring up items that are in the cart because people forget. I do it all the time and I wouldn't want a cashier hounding me before I even finished putting everything down. Anyways, I was pretty much done when I saw her adjust her purse so I KNEW she saw her bag and then slid the bag under her purse.
Me: Did you still want your bulk items, ma'am?
Old lady: What are you talking about?
Me: The bulk items under your purse.
Old lady: Oh, no I don't want them.
I finished the order and she went on her way. The items were chocolate covered almonds. Probably one of our most popular and also 7.99 a pound. Easily a 9 dollar bag.
