Many times I see this attitude and I can guarantee this practice is performed in all our Brazil, the issue of minimum charges and complicated.

I believe that as the internet cafes are companies that provide access to the computer network and therefore offer a service need, because in some cases the customer only wants to make a print or read an email I believe that the collection should not be based on minutes of Value $ you make access minimum of 5 minutes and charge a fee for such access becomes more presentable to say access minimum $ 1.00

this practice should be used very carefully in order not to commit abuses and agrader possiel the client to the fullest.
