How do you feel about me switching all of the sodas at the place that I work?
Are you joking? Why would you switch all of the sodas around?
because I saw a friend of mine go to the fridge and leave one of his sodas. It seemed so much fun to do that.
I see that you found the situation entertaining for yourself, however, you should respect other people's belongings, especially their food. Most people don't like their food items being touched. If you continue, someone will find out and you will create unnecessary tension for yourself at work.
I like to watch people get angry. It's funny seeing people freak out when they get mad.
You shouldn't find enjoyment in people getting angry, but even more than that if your job is to present the food and drinks in a certain way then you need to do that. You could lose your job by doing this.
