So I assume that means all the public. Here is the link to the rules on the town website.

That said, there usually isn't a lot of open space on 1B. I don't think you would have a problem parking in 1A to run in the store. I do think eating meal in the restaurant while parked at the drop off dock would be an issue. Remember there is often Gilford police in the small brick building.
