Unless Rob has something unusual planned, we normally wrap up about six, and a lot of people will make an exit pretty soon after. (Actually, although it looks like they've lengthened their hours again, they've been kicking us out by six since they had their remodel - given the hall entrance is now through the shop, so couldn't be closed separately)
In any case, if 1932 isn't fine, I'm in trouble, as I've booked a 1910 departure. (I'd prefer slightly later, but I don't prefer it as much as it would actually cost me).
