I prefer eating beef noodles,

A bowl of beef noodles now costs 20, I remember it used to be 15
If the price rises to 50, 80, 100, will I start thinking about eating pork noodles? chicken noodles? mutton noodles? replacing the expensive beef?
But if the seasoning increases from 10 to 50, I only add a small spoonful, and in the short term, I won't think about substitution.
So the same logic applies.
