Gornaya Tisa Sanatorium in Kvasy

Information about benefits is not given with the intention that:
you will not notice or will not understand.
This is a typical "formally we have not violated anything".

Everything is great, except that they do not inform about the benefits; they do not warn either by phone or at the checkout.
Last year, they asked about the benefits and said that there were none, after all, it is still not clear whether they were or not. In a telephone conversation this year, it became clear that they seemed to have been there last year as well.
Keep this in mind, because they do not warn about this anywhere. At all checkouts, even in ordinary supermarkets or other establishments that provide health-related services, they ask about discount cards and do not say that it is difficult for them to ask this question (this is just an example).
Take into account that you will not find out about it anywhere, they will not remind you about it, because at the checkout people find it difficult to ask about it either.
Will you see it on the website or ask yourself?
But as practice shows, they can also say over the phone that there are no such benefits.
Everything else is fine, thank you.
