If you were a restaurant owner what would you think of this situation?

So when we were dining out yesterday we encountered an interesting situation. This took place at a restaurant and not a fast-food joint.

As we drove into the parking space we noticed a huge truck parked at the front of the parking lot next to the building. It was a Pest Control truck. So we seriously considered if we were going to eat there or not. We decided to call the restaurant and ask if they were having pest problems. They were so shocked at the question that we were sure they were telling the truth when they said “no”. And later we did see the men that belonged to that truck were simply patrons (as we were seated next to a window).

If you were a restaurant owner would you say something to these patrons? Or would you suck it up for business sake?

On a humorous note what other similar circumstances could be a problem for a restaurant or store owner?
