first day of work = fail

so i had my first shift today, i dont think it went too well :S
first off i showed up at 6:30 for my shift, and the manager says to me "youre late" and that it was actually 4:30 .. great, he said it was his fault that he said it wrong cause its written in 24hour form but i reckon it was just me ==
so anyway i started anyway and i didnt get to go on the registers which is kinda bad cause everyone else has had experience on it except me == great
and sighh just i think it was a bad shift for me ==
gotta work harder for tomorrow and the weekend so i can pass probation period D:
