Got fired on the job interview?

I applied to work as the guy who unpacks merchandise from deliveries and keeps up inventory for this foo who runs a shop and he told me I was going to start working immediately after the interview for "2-3 hours" since he has a delivery today, I said hell no, I got to go drinking tonight and pick up a babe or two and kick it at her place.

Was it my fault? I was expecting to start next week not today!
