I also work every Saturdays but usually, I don't finish later than 5:00 pm GMT. I totally understand that some people working (and therefore not having the choice left to them) would be gutted to miss a tournament with an important prize-poll so I encourage you to talk to Python & Elsse if there are many of you in that case. To me that's a completely different issue than those who simply cannot accept to not go out on a Saturday (or go out later than usual).
