Several of our suppliers claim to support standards, but in reality they support a subset of those standards under certain circumstances.
…which is another way of saying that they don’t really support them at all.
True, you get what you expect most of the time, but not quite always, and when you don’t it can be a problem.
Consider what would if other businesses worked that way. Imagine you regularly ordered a taxi, to take you to the airport or somewhere. And most time, a taxi turns up, where you want it, when you want it. But just occasionally, instead of a taxi, they send something else. Like a golden-feathered chicken, for example.
Not quite what you want when you have a plane to catch, and certainly not something you’d pay for.
