Your personal sprite, a collection of software that manages your day to day activities, has been gathering data on you since birth. It aggregates everything, from personal preferences, to health data, to other smaller metrics like gate. This data comes not only from worn sensors, but also ingested nanomachines, and various other sensors that are shared throughout your personal home and public spaces. Your sprite knows more about you than you do, you control your sprite's settings, and your sprite controls who/what has access to your personal data.
Today, your sprite determines that you're likely to want some cheese. Your sprite checks with your sprites of those in your friend circle and peer group, gathering recommendations from those sprites. Further recommendations are gathered from publicly available sources, various Big-Data AIs providing helpful suggestions that are aggregated together. The selections that are available come from cheese makers all throughout Hawking, including ones made in the city itself, cheese made by the native Grawla, and various space cheeses made throughout the Bruno Confederation. They are moved to a nearby staging area for drones in preparation for the inevitable request for cheese.
When you mention that you would like some cheese, floating holograms are generated nearby of the various cheeses your sprite has determined you're most likely to enjoy. While you are considering your selection, drones race to move the pre-staged cheese to your location. You can look at the packaging of the cheese for more information: Environmentally friendly, biodegradable packaging with only information about the cheese itself displayed on it. Further information can be displayed in mid-air, and largely consists of personal reviews, information about the company that produces the cheese, environmental/ethical concerns, health information, and other informative topics. When you are ready to decide, you just pluck the cheese you want out of thin air and take it with you while the rest are returned to storage.
The cost of the cheese is automatically deducted from your account. Between your level of UBI assigned based on your citizenship/immigration/visitor status and what you make from your job you don't really need to worry about the cost, but a breakdown of the cheese cost and where that money actually goes is sent to your personal account where your sprite monitors generates a report for you on how you spent your money and how that impacts the local economy. Of course, you can engage with your personal finances as much or as little as you want.
You didn't bring a bag with you, since you can always just ask for what you want when you want it. It is generally assumed you'll be consuming the cheese right away, and can send any excess back to your home for storage. You could request a bag, but you can also request similar items like crackers or drinks. When you are finished it is preferred that you throw your trash away yourself, but you can always discard it where you're at, triggering another drone to come clean it up.
