From what I learned from a documentary, the tour guide is responsible for your mistakes. I don't know if that is true, but if it is, at least for his/her sake you do it.

I can answer the McDonald's question for OP since I'm Romanian and the prices are pretty much the same. Big Mac regular menu (sandwich + medium fries + 400ml juice): ~3.6-3.7 eur; large menu (large fries + 500ml juice) costs 50c more.
