This is a universal phenomenon. I went to a Mexican restaurant recently and the dish included a little bowl of "beans." It tasted like lard disovled it hot water with some bean paste mixed in. Another time I went to a local restaurant that had a lot of potential until they made some fresh bright young girl with a degree in hospitality management as their manager. Because of dietary constraints we asked that part of what was included on one standard dish be substituted with something that we could not eat on the dish we wanted. No can do we were told. The substitution would interfere with how they "plate" their food and mess up their portion counting. It would mean someone else ordering the meal with that side wouldn't be able to get it. So I asked them how they predicted the exact number of orders of each item on the menu they would get every night. Ended up walking out in disgust.
We have turned the universe over to braindead nitwits who get taught garbage in schools. Oh, also, vote Biden.
Around here, multiple authentic Mexican restaurants are opening up that are running many of the chains out of business. There are also several food trucks for the taco aficionado. Only people with little money and a desire for a gut bomb ring The Bell.
Food probably already comes to them pre-plated and frozen. Pull it out of the freezer, heat, and serve.
