Guys who don't know Armenian, be careful, it's a common practice in this store to cheat.
The girl with black hair punches the wrong goods every time, more expensive, and when you correct her, she cleans up :)
Today she tried to sell me a small matnakash for 400 drams instead of 180, yesterday she punched three pieces of yogurt instead of one. I've been living here since May, this situation is with her all the time. Keep an eye on her.
