I think my confusion mostly comes from when I was a child, and there was a big waiting room at the train station, for ladies and kids only, with benches for perhaps 50 people. In a corner was a door to the loos. My grandma always insisted we go there and rest, and visit the loo, while waiting for the train, so the seating area was the restroom in my mind.
No phone is easy! If I really have to make a phonecall, I borrow the hubby's phone. I think last time was in 2020 when I made an appointment with the optician! The only thing I miss about it is not being able to take pictures quickly when I'm out somewhere, but I'm thinking of getting a cheap digital camera instead. Or perhaps a phone without a sim card, which would annoy certain people very much 😹
You really are the cellphone rebel aren't you😉
We would call areas like that the waiting room. I believe the term restrooms aren't used for loos these days, but who knows?
Have a wonderful day @treefrognada!
