I'm sure this has been talked about here, the topic has always intrigued me. I'm a big proponent of personal volition and making choices that are right for you as an individual, I'd love to hear your opinion and why. Personally, I have never thought of it as an upcharge simply because I feel time is what is being paid for the majority of the time. I know the situation can vary though.
Providers, do you upcharge for this or not and why?
Clients, If this is enforced as an up charge, how does that land with you? What do you think?
