I always wait for a real person.It is even bigger than that. My favorite example is retraining the customer. Pay the clerks crap money and treat them like crap. They hate their jobs and the customer then has to deal with a pissed off clerk. Then offer self service. People gravitate to the self serve line instead of dealing with the clerk. All of a sudden no need for the clerks. Less payroll, more profit and less management costs.
I smile and chat it up.
Its just better that way, at least for me.
Anyone who hates their job should find a new one.
