There seems to be an idea that buyers of freelance services online don’t have to take any of the same responsibility when making a purchase as they would in the real world.
I get your point that some buyers might need extra assistance. However, in many cases, extra assistance is only required because a potential buyer hasn’t taken the time to read a gig description.
Think of it this way. Imagine you are hungry and stood in a queue of people being served at a busy fast-food counter. There is a menu board on display clearly showing that a burger costs $5, a cheeseburger costs $7, and a chicken sandwich cost $8. Seeing that, would you consider it reasonable to keep cutting to the head of the line to ask things like, "do you do fish and chips," or "how much is a cheeseburger," or "can I have a discount?"
Most likely, you would not do the above. You know that this would annoy the people waiting to be served ahead of you and would be a waste of everyone’s time.
This might seem like a poor analogy. However, this is what a lot of people on Fiverr do when they message sellers. They ask sellers to basically repeat everything that is already stated clearly in gig descriptions, and that is lazy and inconsiderate. Usually, those people are also the least likely to order and the most likely to ask for a discount.
This is an out of date customer service buzzword which rarely if ever applies either online or in the real world. You are also not a customer unless you do actually buy something.
