Hi there.

My guess would be they have an interest in you, but that's only my guess. I don't think it's appropriate whatsoever for your boss to be giving you wine. I think that's unprofessional.

Do forgive me, but I don't understand what you mean by your "main manager comp's me dollars off." You'd have to clarify for me before I could speak further.

If you don't feel comfortable accepting these things, I'd be straightforward and tell them that, especially if you feel like they might be a risk to your health.

I hope I was of a little help.
