When I go to Omsk, I always stop there. My favorite gas station. The toilet is always clean, coffee machines are washed, very polite operators and gas station attendants. Thank you for your hard work!
Very cool staff. Discounts are given for fuel, and they tell you how to get them. The main thing is to say that you are Kazakh, then the price will be like for locals.
The toilet does not work indoors, it seems that the staff simply do not let anyone in so as not to clean it. The door was blocked with a fire extinguisher.
