Flight attendant was a tad rude. We had paid to upgrade our seats and I was told I couldn’t use the forward bathrooms. I’m not talking about business class bathrooms but the ones in our area. She made me go to the back. It was interesting because a few minutes later a few people from the VERY back of the plane came all the way up into the cabin where I was at to use the bathrooms. Pretty dang rude in my book. Not sure I’d pay to upgrade my tickets if I still get treated like I’m in the lowest economy seat while the lowest economy seats get the benefits I paid for!
