No place to go but up!

This is what a typical shopping day looks like for me. Shanghai is so large you can't lay stores out over acres of land...you build them up! This is a picture of my shopping cart on a straight escelator. The first floor is small shops, the second floor is home goods and the third floor is groceries. So if you are on the 3rd floor and finished with you shopping but suddenly realize you forgot the lightbulbs, you have to go back down to level 2 to get them; then return back up to level 3 to check out! I don't make these mistakes anymore, my shopping has never been more organized!
