That is fine, but attitude goes a long way. When one lives like a jerk/beeyatch, they shouldn’t be surprised when one treats them in the same manner.
“The customer is always right” has been abused. It used to be applicable when the customer sincerely believed themselves to be right; now people will intentionally lie to get what they want, and act boorish toward the “hired help” just because they feel they can.
It’s quite sickening, really.
You got that right, Scott.
