I am lucky to have enough money to avoid bullying situations.
I shop at Target rather than Walmart. Nicer staff at the nearby stores.
I grocery shop at the better stores to avoid bad people. I don't eat a lot of food and don't waste it so by grocery bill isn't that bad even with more expensive food. Sometimes it is cheaper to buy more expensive organic food as I can eat it all before it spoils. Though I had learned to freeze stuff like onions and ginger root.
I've also learned to be more assertive. When I'm not sure I'll ask about what is supposed to happen.
Do I need lab tests before the appointment next week? I can't find any papers. So I emailed them and they sent a note to the lab, saving me a wasted trip to the lab.

You are very blessed that you can do the things that you do. I am happy that you don't have to experience this sort of thing.
