You can learn the preferences of each individual by experience, and (within reason) keep to them later on.
I had a friend growing up who hated having doors held open for her, due to an "I can do it my damn self" philosophy.
It was so bad, several times I held a door when she had two arms full of expensive camera equipment, and literally could not open the door on her own without risking dropping it.
Was I violating her preferences in how she wanted to be treated? Sure.
But she wasn't being reasonable. It would have been unreasonable for me to stand and watch her struggle, and eventually drop something.
