Computer store won't help me set up a bitcoin node. Whats going on?

I want to assemble a node and I have contacted a store specialized in modding and assembly of custom-made equipment from separate parts. I want to assemble a bitcoin node on a raspberry, delegating the assembly to the computer company.

I was very struck by the store's response: "Unfortunately we do not support Bitcoin-related issues. We can assemble the parts you want as long as they are compatible with each other and so on. We do not value the purpose of the equipment, being the user responsible for it."

What surprised me is that they talked about this issue as if it was something illegal or immoral, as I would talk if I suspected that the customer was going to use the equipment for some illegal activity. In my country there is absolutely no regulation prohibiting the use of nodes.

What do you think this attitude could be due to? I thought that as an IT company they might be bothered by bitcoin's problem with GPUs and their overpricing/undersupply, but it is not even a mining node so it does not contribute to worsen this issue.

I was simply very surprised by the store's reaction. What do you think about it?
