Sounds like there's a couple of McD's cashiers in here.
You want to know my point of view? That's their job and that's how I treat them. I'll hand you a pocketful of pennies and if you've got a problem with that, go get your manager. I'd be happy to explain to each of you that it actually is United States currency valued at the amount requested for the items purchased.
You can either count it out and therefore.. Do your goddamn job. Or you can pick it up off the floor, because it'll be worth $2 in pennies to me to see you do that.
That's life and honestly, no offense, that's why you're at McDonald's. To learn that that's life and to do your goddamn job. If my job is to fill your cup, your cup will be full. Do you think I get to go tell Google, "awww, but I don't wanna write a bunch of articles and manually submit a hundred back links. That's so much work!"
If you get pissed off over having to spend 30 seconds counting out $2 in change (btw, yes, 30 seconds. If it takes you 2-3 minutes, you're fucking retarded and we found another reason you're at McD's), then go back to your mommy's house and sleep on the couch for the next 15 years because you're not cut out for the work force. What are you going to do when I show you a filing cabinet stacked with papers and tell you I want them ALL sorted by numerical order of the phone number?
Then when you're done with that... Wait, no.. Let's do it by last name. Done? Aww, this doesn't work. How about if we take the first letter of the last name, use the corresponding number (A=1, B=2, etc) and divide that by the 4th digit in the phone number? Organize it like that.
Just do it. That's your job, do it. You're a garbage man? Pick up the fucking trash. You're a window cleaner? Clean the shit out of that window. You're a marketing executive? Make that ad convert, son. Otherwise, move the fuck over for somebody who will.
You will never get any recognition and therefore advancement by bitching about any annoying, petty aspect of your job. If you want to move up as fast as possible, do everything your job entails to the very best of your ability, as fast as you can, with as few "how do I?" questions as possible, as quietly as possible. When you're done, the only question should be, "Thank you, sir. May I have another?" You will be telling your grumbling, complaining, bitchy co-workers what to do soon enough.
Unless you just have a shitty job with a shitty boss. Then GTFO of there.
