some people just have a bit of a superior attitude as well. laelia anceps can be grown mounted, in any bright windowsill even here in the northeast u.s.
people can be funny about things as well.
I was at a vendor's greenhouse in the mid-atlantic region many years ago and I was trying to buy a nice phal lindenii to add to my collection as it was one of my favorite species. one of the owners got very chilly the way southerners can, while under the guise of being nice and polite and told me that none were available and future correspondences were ignored. I guessed later while talking about it with a fellow orchid grower that it was possible she felt I would grow a bunch of them and sell them and undercut her business, and she had admitted that she supplied a few places with them.
some people feel that because they are involved with orchids and that they may have 'special' ones, that this makes the person involved 'special' as well. well, they may be special but not in the way that they imagine! lol i'm sure the owner there at sboe felt that their laelias were so close to perfection that they shouldn't be subject to such indignities as having to grow in heated conditions with glass between them and the sky!
there are such people in the world who breed dogs, cats, horses and such who feel that their products are so superior that not everyone is entitled to own them, no matter how much money they have. I would just try to make orders through the internet where you don't have to talk with someone, maybe have someone else place the order, and if there are any questions via email just have them say they are expert greenhouse grower
