I'm sure they will show you how to tie and pull. In each adjacency guide there is a master layout of each store prototype which tells you where every rack/table should be set.

They will help you a lot with adjacencies because they have the signs and often know what needs to go where.
Set up a system for he/she to get the smaller signs to you and your people so they don't get lost and can be set correctly.
