Thank the sweet baby Jesus reading comprehension is not a major requirement for whatever job it is you do.
And if I were your supervisor I’d give you a break alright, a nice long one.

If you’re in uniform you take personal calls in private and not in public and certainly not within earshot of anybody.
Anything you do and say in uniform reflects on the company you work for.
If you don’t understand any of that you’re a little thick.
