But if people were mostly working Monday to Thursday, it'd be Thursday when people would be in a good mood.
Whereas working Tuesday to Friday, they'd still be in a good mood on Friday, but Monday would now be like Sunday and Tuesdays would suck.
Either way it's a three day weekend and four days work, the first day and the last day are always going to be what they are, doesn't really matter which actual day they are, right?
