Friendly staff. They will always provide assistance in working with the information kiosk. They will advise you on profitable promotions for their products and services.
It is extremely cramped and not optimized as much as possible. The eternal crush and endless queues. Often, not all windows work. To perform a simple operation, for example, currency exchange, you need to stand in a queue of those who make payments and other transactions that last forever.
They work by appointment, it's generally convenient, they came at the specified time, all the papers were ready, left an autograph and that's it, without queues, without problems.
