Bulgaria seems to be incredibly difficult to dive due to the sheer amount of competition coming from the homeless and gypsies. Tourist resorts, as ever, may provide things but it would appear to be hit and miss.
One time a diver Jass was waiting outside an apartment building in Sofia. In one hour, for a regular skip, he counted five divers. None of them walked away with anything, but two had bicycles with baskets full of previously collected waste. Sources seem to show that even bakeries take away everything.
