I worked at a church plant in a gym for 10 years.

When the video introducing the sermon is better than the sermon, you might be a church plant.
When you end each service with, “Could you please stack your chairs in stacks of 7”, you might be a church plant.
If you share one office with 7 people and 4 volunteers, you might be a church plant.
If your green room smells like a locker room, cause it is a locker room, you might be a church plant.
If you’re pastor wears Affliction shirts, you might be a church plant.
If your worship leader doesn’t look like an Abercrombie model yet, you might be a church plant.
If your worship leader looks like an Abercrombie model yet sounds like a wounded beaver, you might be a church plant.

I’ll pick on the mega church tomorrow.
Can you add any?
