in theory, it's actually useful to have some places closed on fridays if it means they're open on sundays. everybody deserves a day off, and staggering them is useful. as a secularist, i'd actually advocate that the day of rest (which i can support as a labour activist, rather than as a religiously mandated thing) be rotated rather than mandated. i mean, something should be open on sundays, something should be open on saturdays and something should be open on fridays; having a multiculturalism that allows the different religions to pick what day they want to be closed on is a sort of brute force application of a rotating day-off, and it's useful for that reason, if not the ideal way to do it.

but, it means you need to actually have some kind of diversity.

and, the problem in this city is that that isn't happening - islam is developing a monopoly, and what's happening is that everything is closing on fridays, which is just as annoying as everything closing on sundays.
