I have a simple and polite request for those of you who are invited to give pre-dinner/lunch/breakfast talks at conventions:
When you see the serving staff start carrying in pans of food and loading them into the chafing dishes on the buffet line, this is your cue to start wrapping up your speech.
I’m going to hazard a guess that, while you’re still yammering away twenty minutes past the scheduled meal service, your audience is wishing you would shut the fuck up so that they can eat. Because they’re probably fucking hungry.
The serving staff is also wishing you would shut the fuck up, because they’ve brought out the food, and they’ve now been standing around with their figurative thumbs up their figurative asses for the last twenty minutes with absolutely nothing to do besides roll their eyes at each other and mouth the words, “Does this guy own a fucking watch?”
The cooks are wishing you would shut the fuck up so that they can clear out the food for this meal and get started preparing the next one. We don’t have unlimited space in the kitchen.
The dishwasher is wishing you would shut the fuck up, because we also don’t have an unlimited supply of clean dishes and odds are good that he needs to get this meal’s dishes cleaned so they’ll be ready for the next meal.
The local health department is wishing you would shut the fuck up too. You see, those chafing dishes on the buffet line are not intended to keep the food hot indefinitely — they’re intended to help maintain the temperature for the expected short amount of time between the pan of food being placed into it and the guests scooping all the food out of it. The health department has rules about how long food can be left in a chafing dish before it has to be either returned to a proper hot-holding unit or discarded.
Everybody wishes you’d shut the fuck up, because the odds are good that the group you’re addressing is not the only group holding an event in the convention facility. And these other groups, who are elsewhere in the building, are also having meals. So there is some rather complex scheduling and timing going on in the background in order to make sure everything goes off when it’s supposed to, and when you keep talking well past the time you were supposed to stop, it throws everything off. Not the least of which is this: it may only be twenty minutes to you, but that twenty minutes becomes an hour of lost time for every three staff members working the event. Make that an hour and a half per three employees if your over-long speech means the cleanup afterward takes twenty minutes longer and puts the whole crew into overtime.
To wrap things up … shut the fuck up.
