Your error in thinking here is assuming those of us here are extroverts or have never been bullied or scolded at work. I DO think you throw that word around a bit too much, seeming to continuously put the blame on other people (pretty much everyone) rather than seeing your own tendency to come on here and gossip, complain, and judge everyone you come into contact with at work who asks you to do your job up to standards. They aren't being unreasonable to expect even new employees to adhere to work standards even from the very first day. Seems unfair, but the customers expect the same standard from every employee no matter what their level of experience. That is what the customers pay for, and the customers are the focus of any retail business.

Most of us have many years of working experience, and we've simply learned that to survive in the work world, you show up on time, you do what you are asked, you complain as little as possible, you follow the correct chain of command, and you realize that there will ALWAYS be people at work who snap at people or are simply just jerks. It generally isn't personal (they're just having a bad moment) and if you'll just let it go and correct your errors in the future, it probably won't even happen again. Try not to assume that one correction (even if impolite) means they are going to have it out for you from then on. People have bad moments. They get snappy and they move on; they don't generally spend time think about it later. We also know some people are just jerks and will always be jerks, and we've learned how to work with and around those people too. Complaining about them probably won't get us anywhere either because they'll always be that way. If you can't work around them, then get a different job, but if you need the job, you find a way to manage their jerkiness without taking it personally. Getting confrontational usually will simply result in getting fired. If you are okay with getting fired, then have at it, but most of us need the money first and will find a way to work around the jerks in the world. The ability to let their jerkiness simply be their jerkiness and not take it personally (they're probably that way to everyone) is a survival skill in the work force.

Retail is hard work and if it isn't the managers snapping (they have their job to do and they aren't always people people themselves), then it's the coworkers; if it isn't the coworkers, it's the customers. You learn to enjoy the people you work with who you can enjoy, tolerate the ones that you have no choice but to tolerate, work around the jerks, and manage the customers (even the rude ones) with a smile even when they are being obnoxious. If you can't do those things, retail may not be the kind of job for you and you may need to look into something different.
