As another poster pointed out requiring you to come in early is an indication the shift was short handed and very stressed. I too believe it was this that was causing your supervisor to be upset.

I've a few more thoughts you must absolutely consider....

Everything is not a response to you. Just because the person was mad didn't mean you caused it. You do yourself a disservice to assume everything is about you I'm being honest here - and this is why you find yourself in trouble and difficulty all the time

You need also to keep your behaviour in check. You can't be so reactionary all the time. Before you act and react you need to pause and ask yourself if you are doing the correct thing.

Ruby this is really crucial if you want to advance in your career.
