This is a bit of a bizarre request, but I'm looking for a place where I can learn a little about what it was like to work at a custom house - the building at ports where imported goods and immigrants would go through when entering a country. The problem is that custom houses are pretty much just museums now, so it's tough to find someplace online where I can research what it was like to work there. One of my MCs for a novel I'm planning out works at a custom house (mostly as a lower-level employee trying to stay afloat in a big city while studying at a university), but I'm not sure exactly what the MC would actually do during the course of a day while there. Anybody got any tips on where to look? Thanks.
