Middle of the week off day lets you get all your errands done with little annoyance from or waiting behind the public, so you get everything knocked out and have your weekends 100% for you.
More importantly, on a 4 day workweek with Wed/Weekend off, you NEVER work more than two consecutive days. Ever. It's fantastic.
Fuck that. Yeah it means you can stay out later Tuesday, but you can't do jack shit Wednesday knowing that Thursday is coming up. I'd rather have another Saturday than another Sunday if that makes sense.
Judging from the other comments it's not for everyone, but personally I love my Wednesdays off. For me it's mostly about dealing with accumulated fatigue due to a health condition though, and I definitely agree about the errands. When I have lots of medical appointments they're so easy to schedule lol
Fuck that I've done schedules like that before . . I'd much rather just take 3 days in a row. Able to rest so much more. Obviously personal preference though!
