Who could blame me for getting ticked off!!

I got called in yesterday for what would be termed as a double double, double shift, double the pay, which is great, gotta finance that trip to Europe somehow right?? So anyways last night before I left to go home I checked with no less than two supervisors to see if they would need me for more over time today. I was told a very very slim chance because they had hired extra people... no big deal. I came home a little beat because there was lots of stuff going on. I figured seems that I wouldn't be needed for today that I could wash uniforms later. I GOT A CALL AT 7 THIS MORNING!!! WTF?????? Now I'm cranky!! Oh well!
