Removing bourbon from shelves is petty and stupid.

I understand the Canadians are upset about tariffs. And they have the right to not purchase American bourbon. By why remove bourbon bottles from shelves ? It's already paid for. Furthermore, innocent consumers who aren't up on current events have no warning. Wouldn't it be better for them to get a last bottle or two and be told "We won't be carrying this item anymore", rather than go to the store and it isn't there ?
