The after work hours must be a culture thing. There's no way you get anyone to show up at a pizza party at work, on a Friday evening, unless you invite peoples families and give two months advanced notice. Kids need to be picked up no later than 16:30 (maybe 16:00), partner get of work at 17:30. You could be ready to go at around 19:00, but that's bedtime for the kids, so now you need a nanny... That seems like a lot of work for a free pizza.
