Customer-oriented??
No, you haven't heard.
You won't get a smile from the staff. You can tell by their faces that you are to blame for all their problems and the only good thing you can do is get out as soon as possible.
Moreover, from the fact that you buy something, they will not treat you better.
In general, with rare exceptions, this approach is used throughout Abkhazia. You just have to give the money, thank you and get out.
If you suddenly need any help - Wi-Fi for a couple of minutes - figs to you. No one is straining to help or suggest solutions.
