Thanks for the continued help everyone!
I'll be picking up my bass in a few hours, I'll look it over and give an update.
I'm still trying to wrap my head around the fact they had no idea what a Squier Classic Vibe was, and thought my bass "wasn't even a squier". Not to mention all the shady stuff they've tried to pull, such as suggesting a $200 tuner replacement, and somehow managing to start work on the bass in the 5 minutes it took me to tell them I'd rather come pick it up.

I just know I don't want guys like this working on my bass.
I'm expecting to show up there and have them tell me they went ahead and put the new strings on it, despite one of the guys telling me "it still has the (original) strings on it" yesterday afternoon when he claimed they already adjusted the neck, and I told them to stop....I have a hunch they're going to try and get every penny they can out of me.
