Wimpy - Wonderpark - Pretoria

This Monday morning (03 Oct 2016) at 9h20 I decided to go for a breakfast at Wimpy Wonderpark. I regularly visit the store.
This morning the kitchen staff were so noisy that we could not communicate without raising our own voices.
A waiter was walking towards customers, with an order in the other end of the store, still communicating (shouting!!) with the kitchen staff.
I approached what seemed to be the manager, and asked if it was really necessary for them to shout as load as they do.
Her reply was "It is Monday and we have double-up breakfast on special".
With 32 customers in the store, it shouldn't be a valid reason for the shouting.
If one goes to any place to enjoy a meal, you would expect to eat in relative calmness.
I ended up at a table the farthest away from the kitchen, which just carried on in the same noisy trend.
Luckily there is a choise of restaurants in the mall.
