There's a small cafe in the building where I work that sells nice sandwiches, salads, and fresh brewed tea. I noticed that they had been pretty empty lately but I didn't think much about it.
One morning, I wanted a coffee and went to the cafe. The owner left as I went in and held the door for me to go inside. I smiled and said hi. Then I waited at the counter. And waited. I leaned over and yelled "Hello!" into the back, but no one answered. I waited long enough to become uncomfortable.
Through the window I could see the owner chatting with the security guard at the front desk (and it was just chatting. He was leaning against the desk and laughing). I went back out the door and asked him, "Are you the only one here?"
"Yep!" He said, with a friendly smile.
Gee, wonder why he isn't doing a brisk business. Usually they're slow, but DANG, he held the door open for me to go in and let me just hang around like an idiot!
