I work in retail. Most customers are pleasant people. Some aren't. While the ones that aren't pleasant are frequently annoying, the up side is we can always laugh at them.
Being rude or condesending to clerical staff doesn't mean you are smarter then we are or better then us, it just means you have issues. Being angry with me because I don't have the book you want in stock doesn't mean I'll suddenly become clarvoyant and know what you want before you do. It just means you are rude. Leaving trash (used tissues, food trash or papers you no longer want), doesn't mean your time is more important then mine, it just means you are lazy or disqusting or both.
While that kind of behaviour annoys me it also makes me laugh. I laugh because it shows people being themselves. People's weaknesses are easy to spot'
