A lot of people seeking tai chi tuition expect to be taught the Art free of charge. This is an interesting notion. It would be curious to see how the supermarket responds to such ideas...
Or the petrol station. Are banks offering free mortgages these days? The optician free glasses?
Do masseurs treat people for free?
What do personal trainers charge?
How much do colleges charge for night school courses?
Are most yoga classes free?
The gym? Piano lessons?
Do they give away free driving licences too?
