BK - re your CostCo adventure
Remember, it wasn't just a Saturday (which is prime shopping time for many families), it was also the Saturday of Memorial Day Weekend. The stores have all been packed with shoppers, and will be all three days (four if you count Friday).
At SuperGiant, we've had all fourteen registers running full tilt. I had one crew of four shoppers at my register yesterday with four shopping carts filled to overflowing, all one order. And this was their second trip! (Of course, they were shopping for a vacationing group of thirty, all down from NYC and upstate, but that's a lot of shoppng!)
It's a good thing I enjoy my work, or this could get overwhelming.
Anyway, since you're not tied to "normal" working hours, and thus not tied to shopping on weekends, you'll probably enjoy the Costco experience more during the weekdays from now on. Smile and say a friendly "Hello" to the staff there when you drop by - trust me, they'll appreciate the friendly face.
