In the restaurant I work in you always start on the normal burgers side (where cheeseburgers and bigmacs are made) either doing dressing or frying buns, because arguably these are the two easiest things to do.
My first shift: first we had to watch orientation videos (about how to keep customers satisfied, hygiene, how to wash hands, general instructions, etc) then we had to fill out question papers, but we were told what to write. Then a manager showed us around the restaurant, then she showed us how to do the buns and the dressing. After a while she left us on our own and we just did the work until the shift was over. It was good, because the job itself is crap but the people really make it better.
About payment, ours looks like nothing compared to British standards, but in Hungary it's not bad at all. We start at around £1.5/hour.
