your observation is likely correct; when I ordered some things from him, I was later told that he was sick and had many helpers; I had two plants one which was sick and died a few days later; emailing got reply that owner wasn't available. later on I ordered something, and asked about and purchased another phal, and received two of them (one free) with regards from norman himself. so, he had noticed the problem and after getting well made up for it.
where I work, it is a very large wholesale greenhouse nursery. in any growing area we have great plants and junk depending on which spot you are in (dripping water, cart fell over etc). when there is a big rush there are a ton of people picking up plants and putting on carts, then getting moved all over the place. no matter how much you may tell people to only pick good plants, your customer is at the mercy of the weakest link in the chain, and you can't be everywhere or check every cart. if you are big, then you need to have many people doing quality control or else you will have misses. if the shipping manager is having a bad day or the boss has jumped on them, then you may get great things or junk depending on their mood at the moment... this is why I always try to be polite when talking to customer service where I can't pick out plants myself, and why I would rather have someone else go to a nursery and pick things out for me if I can't get it myself
