Yes, there are coin-operated vending machines in Flensburg. These machines can be found in various locations such as train stations, shopping centers, and public buildings. They offer a variety of products including snacks, drinks, and even everyday essentials like toiletries and phone chargers. Customers can use coins to make purchases from these vending machines. **

No, most supermarkets do not accept gold coins as a form of payment. Gold coins are typically considered a form of investment or collectible rather than a widely accepted currency for everyday transactions. Supermarkets typically accept cash, credit/debit cards, and sometimes electronic forms of payment such as mobile wallets or online payment services. If you want to use gold as a form of payment, you would likely need to exchange it for a more widely accepted form of currency first. **

As an AI, I do not have the ability to physically interact with self-checkout kiosks at the supermarket. However, many people find self-checkout kiosks convenient for quickly scanning and paying for their items without waiting in line. Some people prefer the human interaction of a traditional checkout, while others appreciate the efficiency and independence of self-checkout kiosks. Ultimately, the decision to use self-checkout kiosks at the supermarket is a personal preference based on individual needs and preferences. **

Yes, the self-checkout at the supermarket is typically video monitored. Many supermarkets have security cameras installed throughout the store, including at the self-checkout stations, to monitor for theft, fraud, and other security concerns. The video monitoring helps to deter and detect any suspicious behavior at the self-checkout, ensuring the security of the store and its customers. **

At the first coin-operated vending machine, which was created in the early 1880s by Percival Everett, customers could purchase postcards for their money. The machine was installed in the railway stations and post offices in London, and for a penny, customers could receive a postcard featuring a picture of the surrounding area. This early vending machine was a novelty at the time and provided customers with a convenient way to purchase postcards without the need for human interaction. **

I'm sorry, but I cannot provide real-time information about whether a specific supermarket is open. I recommend checking the supermarket's website or calling their customer service line to find out their current hours of operation. **

Choosing between a farm shop and a supermarket depends on personal preferences and priorities. Farm shops often offer locally sourced, fresh produce with a focus on supporting small-scale farmers and sustainable practices. On the other hand, supermarkets provide a wider variety of products at potentially lower prices, but may not always prioritize local or sustainable options. Ultimately, the decision between a farm shop and a supermarket comes down to individual values, convenience, and budget. **

It depends on what I need. If I need to fill up my car with gas, then I would choose a gas station. However, if I need to do some grocery shopping, then I would choose a supermarket. Both serve different purposes and offer different products, so my choice would depend on my immediate needs at the time. **
