Sometimes customers know better

Sometimes it is good to listen to your customers. They might have better ideas than you. Also, instructions are overrated and limit creativity, although alternatives aren't always better.:

In 1904, tea bags were invented accidentally. The inventor, Thomas Sullivan, decided that it was cheaper to send small samples to potential customers in silk bags instead of boxes. The recipients believed they were meant to be dunked and soon Sullivan was flooded with orders for his “tea bags”.
