Crunch Fitness – Staff

Hi,
This evening as I was walking past the staff counter the staff member, shortish male, light build, wearing a baseball cap said “ Se you later” then immediately after he said “Go” to me
Good will then ill will all in one sentence
I have had to complain about the staff a before, so now I’m complaining again,
I don’t like people saying “Go” to me as a lot of other people don’t either
Can you find a way for it to stop ?
