Some are of the view that faster and more attractive website is not always better.
In commercial kitchen design - for example, when designing service station dining areas, designers do not aim to make seats comfortable - well they have to be comfortable for a while but it is important that customers purchase as much as possible and eat up as fast as possible.
(My information was obtained from a conversation with industrial experts with a view of producing expert systems to aid kitchen designers.)
Having seats occupied by contented customers is not the goal.
The goal is to sell!
Question: Is it naive to think that such conflicts of interest do not happen in web design?
