If you need a place to stay, you might call a friend or a family member, but the Invisible Man needs a hotel. This is one of many reminders that the Invisible Man has no bonds to the people of Iping, except for his money ("sovereigns" are a type of coin).
"And you know the knavish system of the scientific world. I simply would not publish, and let him share my credit." (19.33)
Of course, being part of a community isn't all sunshine and lollipops; communities sometimes demand work from those who belong.

Mrs. Hall doesn't really understand the science that the Invisible Man is doing, but she's still impressed by it. In The Invisible Man, non-scientists are sometimes suspicious of scientists and sometimes impressed by them. Where do you see this difference?
