A Lesson Learned at Lunch

Was yesterday Groundhog Day?

Why do I ask? Because the same thing happened at 4 different locations during my lunch break. Here are the locations:

1. A convenience store
2. A sub shop
3. A shoe store
4. The church office

This one thing that happened repeatedly taught me an important lesson. Want to know what that lesson is? Stay tuned for "the rest of the story".
