Some restaurants, bars, and museums allow people to pay what they want, but show recommended prices. Online where transactions are effectively anonymous and impersonal, this would obviously lead to freeloading. But somehow it's different when transactions happen in person. I find that I always end up paying at least the minimum recommended price. It's uncomfortable to look someone in the eye and pay less than asked.
When a free service is just a click away, it's hard to convince me to pay. Maybe I'd feel more comfortable paying for internet services if I felt like I had a choice. To do this, internet services could offer a minimum recommended price online, but allowed users to call a customer service representative to lower the price to something within their financial means. I wonder how many people would make that phone call.
