First time I've posted on pedants' corner.
My SIL bought us a metal sign for our attic room, it is in the shape of an arrow and says BATES MOTEL. It clearly should be BATES'S MOTEL. Also, on my DS's report they say 'James' reading' etc, etc. Again it should be James's reading.
Does everyone agree, or do you think I've got it wrong?
