I lived in an all male except me household. I was outnumbered so I left the seat up. Who cares if the dog wants a cool drink that doesn’t taste metallic?
Even though this was only for about 15 years I never forgot to put the seat down for myself.
I had a roommate in college who was the youngest of 8 kids, and the only boy. He said the best part was getting to go on 3-4 day hunting or fishing trips with his Dad just about every month.
