Well, this thread is about what the cultural norm is for tipping in Indonesia, not Egypt, so I'll be brief. In Egypt, as I'm guessing you know well, it's a cultural thing to keep the machinery of commerce running smoothly by handing out small amounts of money (usually well under 5 euros--you ARE generous!) to just about everyone you deal with--baksheesh, I think they call it, correct? Is it a tip? Is it a bribe? Is it its own unique thing unlike anywhere else in the world? Who knows. But the point is, that's the cultural norm in Egypt. There are other threads in which someone asked what to do when in Egypt. In the US, there is the cultural norm of some closely fixed percent of the bill, which as you point out, has crept up over the years. But I digress. In Indonesia, the cultural norm is what several people who either live there or travel there frequently described in the first few pages of this thread.
