Why is there no red wine in the bar?

Red wine doesn't work in bars. There is no red wine in the bar because the environment in the bar is noisy, not a place to talk about things. Most people drink red wine in a quiet hotel room, sip it slowly and discuss the problems that need to be solved, but the bar is a place to relax and release pressure, which is not suitable for talking about things, and the role of red wine cannot be brought into play.
