Google Maps error causes me a bit of consternation

I arrived in Liberal, Kansas after dark, Googled the location of Wal-Mart where I hoped to spend the night, drove there - and found no Wal-Mart. It took a few minutes, but I found it lurking a few blocks over. I only recently started using Google Maps to locate businesses and now wonder how often this kind of thing happens.

Night camp:
