I have some people in my team who take Wednesdays off, mostly because they have kids and the schools are half days on Wednesday. Personally I'd take the 3 day weekend everytime. Shops are also open on Fridays so that point is kinda moot. And the fact that people have to wait for me is not really my problem. They also have to wait 5 weeks for me when I'm on holiday; it's the organisations' responsibility to make it work not mine. But if we all go to work 4 days, it might be beneficial to have 50% take Wednesday and 50% take Fridays.
