I can give a short and long answer.
1. The short one:
Because you're in Bulgaria and here absolutely anything is possible !!!
2. The Long one point by point :)
1. Probably cause they're buying the cheapest things that dealers offer them.
2.Cause nobody is following the rules to drive a car ! (I like to Kill them All)
3. Murphy's Law - It's really strong in BG :)
4. For the streets cause they don't have enough money for Labels  + the fact the a lot of people like to steal, collect them . For  SU I don't have an answer
5. oooooooo , They're nice kids like 1 guy answer : Be happy that they're not listening chalga - It's a miracle !
6. Second-hand is national sport here :)
I saw really fun Ad - We are offering clothes with history for people with Future
7. They put cashkaval cause it's cheaper and like 20 years ago when nobody didn't know anything about the parmesan  and mozzarella - What do you think that we didn't have Pizza we had it with sirene i kashkaval and of course everybody loves it in that way, so if you want it in normal way you can say it when you purchase
Excuse me  - it's not a  patriotism but THERE IS NOT SOMETHING LIKE GREEK FETA - JUST the bulgarians didn't make the payment for the international patent and this bastards steal it ! Like the  Sourly Milk all the Japanese are eating real bulgarian Кисело Мляко, unfortunately we are eating fake shit cause they put only shits in it :(
8. This one is too long to be explain. Short - cause they never been do it in the past and they need time to be learned and of course some people want to make a lot of money before that  !!! The F*ckin Mafia I mean
9.I'm askin' the same I love red head women :)
The short answer is that  85-90% of  ladys in BG like to look the same  and when the new shitty style is here you can see all the women on the street  like twins , it's not only for the hair, it's for everything - clothes, music , etc  :)
BTW This is taking their beauty cause they really pretty at all !!!!
10. The Shortest ONE : THIS IS COMMUNISM !!!
(Which is back for the last 4 years with this government)
