Hello, questioner! I am Jia Ao, and I'm here to help.
You asked about interpersonal communication, right? The manager asked you if you'd ever drunk a double-skinned milk tea because of a conflict over it. You instantly felt that the other person was despising you, so you answered forcefully. You want to know what's wrong with you and how to adjust your mentality.
Let's address your problem together and analyze it.
Accept your emotions as they are.
Learn to deal with your emotions before solving problems when encountering conflicts. You originally wanted to make a purchase in the store, but the shopkeeper's blunt question provoked a lot of negative emotions in you. You must have felt offended and speechless: "Does the shopkeeper look down on me?" "Does he despise me so much?"
This is very common. If I were in that situation, I would also feel very helpless and angry. Accept your emotions as they are, allow yourself to temporarily feel down, and then adjust your state of mind.
Enhance your self-worth.
This can be a big deal or a small deal. A normal person would feel offended and rude, and would just argue back and get it over with. But you seem to have overreacted, feeling that the other person despises and looks down on you. This is generally an illusion. Perhaps the manager was just in a bad mood at that moment and didn't mean to look down on you. You think this way because your sense of self-worth is unstable, and you doubt and deny your own abilities or value. You need to boost your self-worth and let your emotions stabilize gradually, so that you no longer let other people's opinions and judgments affect you. "Walk in other people's shoes and let others talk!"
The self-projection effect
It's time to face facts. You feel that others look down on you for any little thing because you are too inferior inside. You even look down on yourself. You impose your subjective will and emotions on other people, and you feel that this is an unacceptable fact, so your reaction is so emotional. Relax. Others don't know you, so how could they look down on you so easily?
Boost your self-confidence constantly.
The root of all problems is a lack of self-confidence. You must learn to boost your self-confidence constantly, identify your strengths and advantages, work hard to improve yourself, enrich yourself, be proactive, overcome your inferiority complex, and only when you are strong and confident enough will others look up to you, respect you, and you will not feel belittled so easily.
Adjust your mentality positively.
Ignore those who despise you. Don't care what others think. You don't need their approval. For people who really despise others, just ignore them! The more you care about it, the more trouble you will have. Just ignore it and be yourself. It's enough. You don't even have to give them a second glance.
Be happy.
Live a happy life and live it well. They'll think twice before looking you in the eye again!
Today is the Mid-Autumn Festival, so have fun!
I hope my answer helps. The world and I love you.

I can totally relate. It feels like the store manager was a bit rude implying you should know what doubleskin milk is. I would have felt taken aback too.
It seems like the store manager made you feel judged for not knowing about doubleskin milk. That's not a great customer service approach, right?
The store manager's reaction wasn't very welcoming. Anyone can be unfamiliar with something, and it's okay to ask questions. Feeling dismissed isn't nice at all.
Feeling like someone looks down on you for not knowing something can really sting. The store manager could have been more helpful instead of making you feel that way.
Sometimes people in stores forget their manners. The manager should have explained what doubleskin milk is rather than making you feel ignorant for asking.
