You do not know the suppliers, you dangerous for your customers. 14 stupid questions I received

I received a strange request from a customer, one of those super structured companies where you as a supplier always have the impression of not having a point of reference; there are always new employees, they often seem to be there by mistake, it is clear that they do not know who you are, that you have been working with that company for many years but, and it is worse, they do not seem to know what they are talking about when they interfere in audio voice over issues.
As in this case in which they sent me 14 questions that seem to come from total inexperienced people.
Of course, my first reaction was gut. But how? You do not know your suppliers? And what service do you expect to give to your customers?
I had doubts about this request, I let myself be carried away by thoughts, until I saw all the darkness of an approaching storm.
No, I do not work for you!
But in the end? Well, I will tell you in the end.
