People tend to check in during these times:
Wear ear plugs. Music is terrible here!!
Beware of fuel perks & BOGOs! They don't always come through when you check out. Make sure to check your receipt before you leave the store.
Once again waiting in a long line! They need more lanes open!
Never more than one lane open before 10am. And that seems to be when everyone shops. Hence the long line I'm standing in while I type this.
