I budget about 50zl a day for expenses-food, smokes, beer etc, but obviously some days I pay more, especially when I go to restaaurants.
I'd say the same as Scottie.
50ZL per day is a good budget.
And then on the weekend's maybe 100 per day.
That'll still give you around 4-500 ZL for unexpected expenses.
I am assuming since you do not have to pay rent, that you also do not have to pay bills?
