I fully agree with you. It is absolutely not an offense to offer a bottle of wine and this the most common gift along with flowers. As you said, there are plenty of reasons to not serve upfront the one just offered like because the host has already open in advance a bottle of red wine for oxygenation, or the guest has bring a bottle of red wine while the main course will be fish, or the guest bring a bottle of white wine or champagne that is not cold enough to be enjoyed properly, etc etc.


Things have changed a lot since Macron laws. I live in Paris (in a non-touristic neighborhood, purely residential) and all food supermarkets (like Monoprix, Franprix and equiivalent) are open all day on Sunday for at least 2 years. Exceptions apply of course.
