I agree with 3 of the 4. I think it’s okay to ask if you can buy something early-the market should have a way to answer that question, and sometimes it’s allowed. And yes, sometimes stores do let customers in early.
I also think when someone asks about a farmer’s life (like when do you get up?) it is only to learn and to connect. If it doesn’t offend you, you can use the moment to teach other people about the life of a farmer. But dear shopper, do beware the grumpy (tired) farmer!
