Working Lives Krakow: Student
Six very different Polish people from Krakow talk about their lives.
Karolina Kasza combines her part-time degree course with work as a waitress.
Tourists flock to the picturesque city in the summer, meaning she can double her wages of around $200 (£125) per month with tips - but during the winter things can be tougher.
She wants to continue working in hospitality when she finishes her studies, her goal being to run a hotel.
