Bad headache at work all day!

I got a bad headache all day at work. It was started by those stupid questions from the customers. Yes! Customer is always right but they should put a limitation to themselves and use their common sense somehow if they have it! Pisses me off even they saw me working hard and very busy in the bottom line they just don’t care at all! All they did was bug other people. It was a busy day today at the store and even if I already did my best to go home early but I was late fifteen minutes and got overtime again. Well, it doesn’t matter as long as I did a well-done job! But my head hurts badly and I can’t stop it! Maybe I just have to go to bed now. See yah tomorrow…
