Australians might soon be expected to tip as frequently and generously as Americans, new research warns.
The study assessed the origins, drivers and social consequences of tipping in Australia and the United States.
Researcher John Frank Burgess said tipping flourished in America because a deregulated labour market.
He warns that if Australia heads down the same path then "sooner or later tipping will become normalised".
"People in Australia need to decide what kind of country they want to live in," he said.
