The customer is the boss, period. They say poop runs downhill.
Nope, it runs uphill and any good manager knows that. Terrie
said she has never walked away from a customer and neither have
I. I have had to apologise a few times though. Bluey said the
customer is always right. That is a mindset that no one has these
days, unfortunately.
The managers and coworkers are immature. That is their problem.
If YOU choose to get upset over their words than they are controlling
you. Take a deep breath and let it go.
Sounds to me like you are a great employee and you have nothing to
worry about. Managers are easy to replace. Good, customer oriented
folks like you are not easy to replace.
