Everyone wants nugget numbers posted on every menu.
Fair enough.
Here's the question:
If you post chicken nuggets are 3 piece or 4 piece who is more likely to order?
The person who wants 2 pieces is going to get a good deal.
The person who wants 6 pieces is going to need to order two.
So your customer base isn't the purchasing pool because you won't convince the 6 piece person to come in.
It's the people who only want 2 nuggets that are willing to order.
That's the difference.
