I understand people here debating veggies and fruits or meat. But Christmas trees? How often does one buy one? Once a year? Might have been a fluke? Or do you have a compelling reason to relate this to Brexit?
I don't think it has anything to do with the EU or not. Rather I think there has been some industry wide "efficiency gain" in picking/harvesting/cutting stuff that make the product worse when you buy it.
Obviously the Christmas tree can be a fluke. But so was my mom's and my tree the year earlier. In my childhood they still had like moist resin and smelled alot. But the ones you buy nowadays are dull.
