Generally in Australia a persons wages are meant to cover their services. Tipping is given for good service as an extra but it is not seen as expected. So with that cultural heritage it seems that I might be wandering into hostile territory, LOL

From what I hear, it seems it is a hidden surcharge on services in the USA.

I would appreciate some advice on what is the norm on what you are expected to tip both in size and for what services.

One bit of culture shock I am to experience LOL
