“Waiter” is common gender.
Yeah, but whatever restaurant I go to, I’m told “your waitperson is so and so” .... waitperson. How lame. It’s like chairperson. Don’t these idiots know that it ends in “son” which is masculine? Can’t use human ‘cuz it ends in ‘man’ can’t even use Hu-person cuz it ends in ‘son’ ... how about Hu-people???
