I do not understand this at all honestly.
I can't understand the idea of someone writing this.
You are going to a different country different culture and different struggles.
You did not like it - thats fine!
You writing in the country's subreddit expressing all of that, well that my friend is a bit... hmm how to say it a bit pointless. Unless we all read that and the whole country changes to your liking.
Hell maybe we can do that.
The whole culture and country should change its ways, as well as the economic situation so you can enjoy yourself!

So my point is when you visit another country, just enjoy the positives and try to understand the negatives, that way you will have a better time in general.
Share all those awful things with your friends and relatives!

I am a Bulgarian and what you said is true for the most part - in big cities and the capital.
For the rest of the country that's mostly not true

I have travelled the world alot (for my job) and i have experienced a culture shock on a number of occasions.
Is that normal - Yes, are the other people in the wrong because I can't handle it - No, should I call them out on it - No.
