I would like to know why the staff that works in this location are so mean, and do not have the slightest empathy to the client

I've only been to this location once and that's mostly due to the poor service I received. This specific location gives Whataburger a bad name.

I always have problems with this one.

I have not personally had that problem I have always been treated with respect and kindness. Maybe you just got someone that was having a bad day.
