It’s perfectly possible to be professional and not come off in the way you’re describing as desirable.

In fact, acting in the way you’re describing is itself a negative social rule that will lose someone business opportunities. Because people with value that don’t want to operate in a coldly transactional environment will be turned off by it.

“I don’t owe you anything other than money for the task you’re doing,” is a good way to eliminate a sizable portion of potential high-quality employees.

The further up the economic chain you get, and the more relationship or service oriented the work is, the more important this becomes.

It doesn’t make you seem professional, it just makes you seem like a difficult person to deal with, and thus someone to avoid.
