I didn’t see an appointment for today, should I sign up for one tomorrow or the next day?

Please do not sign up for an appointment for any day until the greeter tells you to. When you just sign up for an appointment for tomorrow or the next day, you’re taking an appointment from someone who actually needs to come tomorrow and it takes a lot of staff work to clean that up.

So unless you actually plan on leaving and coming back for an appointment tomorrow or the next day, please wait for instructions from the greeter.
