CAB have been charging service fees on credit accts and cards since the 1980s, well before surcharge allowances in 2003.

Allan Fels has an agenda given his background and has no general idea about the taxi industry
A good analogy of the taxi industry worldwide is given at http://www.taxi-library.org/revdoor.htm by Professor Dempsey who quotes from a powerful essay by Garrett Hardin, "The Tragedy of the Commons".
This basically rebutts economic theory and people like Fels as far as the taxi industry is concerned.
