Costco is such a family friendly place. My kids love going there.

They've made some deliberate decisions to make it family friendly:

1. The aisles are wide so the whole family can walk through the store together.

2. The kids love free samples

3. The food court is a great place to have an inexepensive dinner.

4. The store is designed so there's nothing really to grab at ground level if you're a little kid. Everything is up higher.

Contrast this with a standard grocery store: small aisles and tons of little things on the shelf at ground level (including random toys) that can get grabbed or knocked over. Every time I take my family to Albertsons I have to pick a dozen things off the ground that we accidentally knocked off.
