​My dad’s business partners have no idea what they are doing

My dad has partnered up with 2 other men to create a parking complex and it includes a fast food/ cafe place. People will be able to order fries, burgers, coffee, fruit etc. My family until now has owned a very busy fast food restaurant. It’s been in business for more than 20 years. My mother is the main manager and she is the one that has been organizing and ordering the supplies.

My dad and his partners keep calling my mom to ask questions but they don’t listen to her. One of the partners has hired his kids and they made themselves in charge despite not knowing a thing about running a business. They have called a friend of theirs who owns a struggling beach bar to help.

The more I hear about their decisions the more flabbergasted I am. – Only 3 or 4 cutting boards and 1 knife in the kitchen. It’s a safety Hazard and extremely illogical. Best case scenario our mangoes taste like onions and worst case scenario someone dies. -Only one deep frier. According to that friend of theirs we will only have one deep frier and we will serve all the fries with salt and oregano. We don’t want to be fast, screw the tourists waiting to leave. We will make only one batch every 10 minutes. What about the chicken nuggets? Idk -Only pork burgers. Half of the population doesn’t eat pork but the beef patties are slightly more expensive.

I won’t talk about how none of the people in charge don’t communicate with each other. The suppliers call my mother all the time because they can’t reach them and when the order is slightly wrong the partners get mad. Or one says “I will do the order” and later the other calls my mom to ask her if she ordered.

The business is a mess. My father doesn’t want to butt heads with his business partners for some reason and keeps scolding my mother for being argumentative. This investment was huge and I don’t want to see the business failing. I will have to work there this summer because they don’t want to employ people.

Is there anything I can do or do I have to suck it up?
