My son lives near by and shops at HT often. He says SC is often packed. We went back later and only 4 slots open.
maybe they've gotten busier since I've had to commute near them for work daily but every time i'm in the app it doesn't seem that busy. When I have been there it's almost always a lot of model 3s charging which to me means one of a few things 1) they aren't local 2) they need a fast charge to head out of town 3) they don't have local charging as @magellen55 noted or 4) they just enjoy paying over 2x the local rate for kwh
the SC up north raleigh by target always used to be camped by free charging S and X but I dont' think that's nearly the issue it was anymore.......who knows though maybe i'm wrong.
Luckily NC is getting a lot of new SCs being built so it's only going to get better I think.
