I can count how many times per year I get 200 ZL bills on the fingers on one hand
Same here - though I've noticed it getting more over the years. One tip with bankomaty is to use ones that have smaller notes and deliberately choose an odd amount so at least there are some 20s.
500zl bills are ok when paying huge purchases but useless for daily buying...
Absolutely. I wonder who will use them the most?
When early in the morning, we buy something for let's say 17.50 and we only have a 100 ZL bill, they don't like it...
Some (most?) places, even in the city centre don't start the day with any sort of float of change. Makes no sense, really.
