I worked for Starbucks in my 20s and the hours were awful and stressful, they paid me minimum wage with a master's degree, they never gave me the benefits they agreed to give, and there was no work life balance because all I was doing was working for Starbucks. Not to mention customers have high expectations of Starbucks products so they are rude, yell, scream on occasion and have such high expectations you'll injure yourself trying to please their clientele. If you make mistakes, your manager will fire you. Not to mention the bosses were stressful to handle because they also yell.
Too many. All around bad.
