That isn't the same thing at all.This is new for fast-food places, but not for most other restaurants. Many have similar if not identical food yet charge more during dinner hours. Mandarin Buffet has been doing this forever and also charges more during holidays.
The change will certainly turn off the regulars, but the occasional customers likely won't notice.
These are buffets first and foremost, and they have more menu items during the dinner and holiday times. More food options at the buffet means higher prices.
So, not the same thing.
It's not even in the same ballpark.
In fact it isn't even the same sport.
