Background on topic here
It mentions in the article that the surcharge can only be to cover costs and not to increase revenue.
Our local pizza shop, which enjoys a monopoly (as there is only one pizza shop in town) has recently introduced a 5% surcharge.
I believe that this is too much.
I could vote with my feet but that would mean no pizza, and that IS NOT an option, so I pay via eftpos.
Anyone know what is considered a reasonable surcharge?
