Here you guys go, learn from my mistakes:
Right after I graduated high school, barely 18 years old, I got a job working for a large grocery store in the area. I was so excited about the money that I'd be making that I never once stopped to think about what the job would actually be. I imagined long days of smiling at customers while scanning their groceries and stuff like that... never once was I prepared for any other aspect of the job.
I had three days of in-office training - taking tests on computers and shit like that. It wasn't hard by any stretch of the imagination, but it wasn't fun either. So I suffered through those days with the growing anticipation of working on the main floor, interacting with customers.
My first day on the floor would be my last... in the staff room we had a schedule for shopping cart returns. It was a magnificently hot summer day and I thought to myself, "How lucky!" My name wasn't on the board at all... but poor Stephan with a "PH" - that miserable bastard was going to have to go out there every half hour to fetch carts...
So I'm standing at my checkout line and I'm learning how to bag groceries... a few hours go by and I realize that I'd like to take a break. Knowing that I should have had a break after two hours, I made my first mistake: I approach the manager - a bald dude by the name of Moe.
"Moe, I was wondering if I could take my break?"
"I TELL YOU WHEN YOU TAKE YOUR BREAK!" he replied in frustration. "WE DONT ASK FOR BREAKS HERE! I TELL YOU!"
I wanted to cry... I mean, surely I didn't do anything that terrible, right? Well, I must have, because this fat bald man wanted to eat my soul.
So, soulless, I went back to my checkout line and bagged groceries, all while desperately craving the chance to go to my car and sit down. My feet were NOT use to standing, that's for sure. Finally, Moe comes to me and he says, "Go ahead and go out!"
...I misunderstood him, apparently. See, based on our previous interaction, I took his comment as "Go ahead and take your break." In real life, what he meant was "Go ahead and go get the carts!!!"
So I come back in and get yelled at for taking my break... I explain to him that I misunderstood him and that I'm confused because my name isn't on the cart return list - it isn't me, it's Stephan with a PH!
"WELL, FOR THE REST OF THE DAY, YOU'RE STEVEN WITH A PH! NOW GO GET THOSE CARTS!"
So pushing the carts back in, I whack my head on a brick. It's like a million degrees Celsius and I'm just pissed off by everything, mostly the way in which he talked to me. I mean, giving me a whole new name? I don't think his power extends that far!
So I'm pissed, go out to my car and get a different shirt, and return to the store. I walk up to Moe and told him he was disrespectful and rude, and that I'd no longer be working there. I handed him my shirt and walked out the store, never to be seen again!
...
So yeah, don't quit just because you're pissed, as I later learned from friends at the store that Moe was never like that to anyone, and that he was having a rough day because of his ex-wife.
