That really sucks. I've had coworkers like that before, pretty much everywhere I've ever worked. There's always at least one.
I wish I had better advice for you. Usually with them, I just keep my head down and try to stay off their radar as much as possible.
Yeah, my family currently has R but next year we need to buy an L for most of the reasons listed above. I'm just glad both options are available, it's always works out better for consumers when there's more choices depending on your needs.
