I've been at this store a few times and have had friendly staff assist me. Some are cool about writing on paper if I ask for it. Some will understand gesturing/pointing. There was one person who knew some ASL at the store; I don't know if she still works there or not.
It's always nice when there's a staff who can sign to Deaf/Hard of Hearing customers! I plan to go back there again soon and will ask around to see if she still works there so I can say a quick hello and thank her again.
