You’ve heard this many times and you may have said it to others.
To me this is a poor excuse for a greeting. I say that because what if the person you say that to is having a bad day? Do you really want to know how they are feeling?
Years ago when you heard ‘How are you doing today?’ you automatically thought - here comes the sales pitch. If that is still true, why would you want to put up a barrier before you even got to know someone?
Why wouldn’t you just be pleasant, have a soft attitude and be interested in the person you are meeting?
It is better to build rapport first, isn't it?
