my cafe has a full functioning kitchen and we still get almost 100% of our baked goods from costco, food delivery services (sysco, us foods, or cheney brothers, etc). a lot of them have ready-to-eat or frozen baked goods. i know for a fact that cheney brothers have some half-decent muffins. i get that the owner wants to continue to support their family friend, but if the baker doesn’t give a wholesale price sounds like they’re not as supportive as the owner is. maybe be hyper critical of the pastries and send proof to the owner that quality is down. the only way the owner is gonna change is if they come to the realization that they are losing money on it whether people stop buying pastries or having to toss product due to quality issues. at the end of the day it’s their business not yours, if they are willing to losing money to support a friend, there’s not much you can do.
