That bought back a memory from several several years ago. A lot of stores had switched over to the auto opening doors, especially this one particular chain of stores. The small town I lived in at the time had one of these chain stores but they had not made the switch yet. As i was approaching the store, I saw a small kid maybe 8 years old walk right into the door, and fall on his ass when the door did not open. He backed up and slowly approached the door waiting for it to open. Then I saw him step back and start waving his hands at the top of the door. It was funny to watch, I eventually got to the door and pulled the door open for him, and told him they had not upgraded yet.
