I remember the days when a fast food burger actually tasted like a burger.
Now you have to go to a Five Guys or an In and Out.
Every resteraunt started out trying hard to get your business, and using the best servers, recipes, and contents to have you wanting more and more. The betrayal came when they established themselves completely by having your complete loyalty to them as a customer, and this as based on your overall experience with them, but then they start looking for ways to increase their profits by taking away from your experience in hopes you wouldn't notice, and if you did notice (well they didn't care at this point) because they were established and no longer needed you anymore.
So ever so cleverly, they start using less quality meats and vegetables, less quality servers and cooks, less quality service as they enrich themselves off of the monopoly they are then enjoying.
Now how to change these things is anyones guess......Maybe one should make sure to support a smaller operation in which you have more input and control over is the answer.
Forcing resteraunt operations to uphold standards by a resteraunt watchdog group is another way, who knows ?
