It’s from a Jumbo supermarket in Argentina.

Many Jumbo supermarkets in Argentina have adopted self-checkout systems designed to streamline the shopping process, especially for customers with fewer items. These express lanes typically enforce a strict limit of 15 items per transaction, helping to reduce wait times and improve efficiency during busy hours. The signage at these lanes is straightforward, often stating "Maximo 15 unidades" which translates to "maximum 15 units." This clear communication helps shoppers know upfront about the limitation before entering the lane. Additionally, the instructions emphasize simplicity in the checkout process, usually broken down into clear, easy steps to guide users unfamiliar with self-service technology. Such systems not only benefit shoppers by expediting their purchases but also assist the supermarket in managing queue flow and reducing congestion in traditional staffed checkout lines. This makes it particularly useful for customers who want to quickly grab a few items without waiting in long lines. The self-checkout lanes at Jumbo often support multiple languages and include helpful prompts on screen, making them accessible to a wide range of shoppers. Moreover, these lanes are sometimes integrated with mobile payment options, further facilitating a seamless transaction. While these express lanes are very convenient, shoppers are encouraged to adhere to the item limit to avoid issues at checkout. Exceeding the 15-item cap can cause delays, as store staff may need to intervene or redirect the shopper to a regular checkout lane. Overall, Jumbo's approach to self-checkout with an express lane item limit reflects a growing trend in retail to leverage technology to enhance customer experience, reduce checkout times, and maintain efficient store operations.
