A game I only bought because someone else wanted to play that together on a private LAN party. That person then announced that they couldn’t show up. And since I was terribly uninterested in playing that game on my own and only bought it for just that occasion, I refunded it after that news.
Probably 5 minutes or so. 10 if I include the time spent driving there. Usually it’s quiet enough that it’s not waiting in line but rather waiting to have everything sorted out.
