Just don’t go.
Do not work here if you're sensitive to words. It's basically a conveyor belt of calls back to back of angry customers. If you dont like getting help this job suits you.
Be on time always show up dont miss any of the work
Do your best.
Just show up and say "yeah nothing gets under my skin, I love people!" and you got it...
Work there if you need a job that pays ok but dont expect anything but a hard time.
