I stil reminice my holidays in Poland - terrible time for me
I worked in Władysławowo as a kitchen assistant.
Firstly - I worked with Janusz and Maciej in Restaurant Something about 50 days . July was free but in August and July I worked hard .
Everyday I was cooking cutlets and soups . I was working in the basement So I had seen something special . But in Monday the oven caught on fire ,that was terrible
My holidays were great because I had some practice ,that would help me in my future .

I still 'remnice' - co miałeś na myśli? - HARD TIMES for me.

My holidays were great because I ACQUIRED/GAINED SOME EXPERIENCE (uzyskałem trochę doświadczenia - zapamiętaj) WHAT MAY/CAN HELP ME IN THE FUTURE.
