Is this easy enough to do, if you're not already used to the opposite? I mean, I have no issue sleeping in the day / staying up at night, so it should be okay I guess? Or does it kind of kill you? And should you get paid more for night shifts with shop work? Well, you should, but do you?, is what I mean. Working in a shop completely outside of trading hours is strange though. Can't imagine there's an awful lot to do.
And is it better to sleep after getting home from a shift, so say about 7am to early afternoon - or before a shift, so early afternoon to about 9pm? I like questions.
