I agree with the others - if you have decided to maintain a rate of $40 a day after all than ALL clients should be paying the same rate for the same service .... so unless they have a 'specialty service' of some sort that warrants an additional charge they should not have their rate go up if you are not raising other's rates for the same service ... so for example I have clients who pay more than others because my fees are based on a maximum nine hour day .... if you use more than nine hours a day you pay $5/half hour each day....so I have some clients who pay $32 a day and some who pay $37 a day.

I know I get frustrated and well honestly angry with feeling taken advantage of when I hear that peers with Rogers Cable or other service companies are paying LESS for the exact same service as I am - IMO it is poor customer service and retention practice to have 'unfair fee structures' and people will spread negative word of mouth about that kind of treatment!
