Best to just focus on being professional, doing a great job and the best job that you can then to worry about people's moods towards you. If you are polite, friendly and easy to be around, then there is no reason to be mad at you. But if you are acting out again in your work environment, yelling at people and goofing off as you have told us about in this job and others, then yes, people could be angry with you. IF you are acting that way again.
