Pretty unreasonable?

clientsfromhell:

Client: I need a flyer designed! It goes to print tomorrow morning!

Me: I don’t usually take such tight-deadline, no-notice work. I’d need you to wire across half of the payment as a deposit first.

Client: How am I going to do that!? Our accountant will be asleep by now and it would be pretty unreasonable to wake him and ask him to work at this hour!
