The words and phrases you use when speaking to groups can build rapport or trigger disconnects. That could be based on different cultural, age, or sex perspectives.
Sometimes the gaff can seem cute. Other times the misspoken phrase might send your audience off on a tangent. They might be wondering what that phrase means. They might be wondering about your credibility if you used such an out-of-date phrase. The point is that they might be wondering many things other than accepting your intended message.
The speaker talked about Crisis Management and how to prepare. He suggested that it was similar to noticing the engine warning light on your car. When you see the trouble light warning you of a problem you should take your car to the gas station to get it checked.
If you don’t understand that last statement, you understand my point.
If you remember taking your car to the gas station for mechanical work then you are probably reminiscing about the 1970’s or earlier.

This audience clearly included many people who would not understand this analogy because they were too young. These were people who go to a gas station to get gas, coffee, snacks and cigarettes. Those last three items weren’t available at the gas station when you took your car there for mechanical work.
Be aware of the analogies, phrases or jargon that you use because these words might alienate, distance or confuse your audience.
