Expectations for working on weekends

[Travis Heppe]

What parts of the real estate industry tend to shut down on weekends, either in part or in whole?  I understand that there may be variance between individuals and companies, but what are the industry norms for:

agents?

loan brokers?

title companies?

lenders?

real estate lawyers?

inspectors?

Actually, I've just ordered that list from most->least likely to work on weekends, but I'm wondering what everyone else would expect.
