This was at a time when mcdonalds first started serving good quality espresso coffee at the main counter as opposed to filter coffee. I was about 17 at the time but due to poor health this was my first job, so I was very shy and naive. I clock on and a man I didn’t serve approaches me.

customer: “I ASKED FOR A BLACK COFFEE YOU BLOODY IDIOT! IS THAT REALLY TOO GOD DAMN HARD FOR YOU!?”
Me: “oh! I’m really sorry sir, let me fix that up for you right now.”

I start a new black coffee and go to tip out the old one, and am surprised to find it is indeed black. Not wanting to further aggravate the guy, I just give him his new one.

Me: “here you go, one long black. Sorry about the mix up.”

He opens the lid, and then slams it down on the counter, splashing it everywhere, and yelling expletives at me, insisting that he has been given the wrong coffee again.

Me: “I assure you sir this is a black coffee. That’s not milk, see? It’s just the crema. It’s like, the natural oil of the coffee and is an indication of a good quality coffee bean.”
Customer: “I DONT WANT CREAM, I JUST WANT A LONG BLACK, COFFEE AND WATER”
Me: “Yes, this is a long black, just coffee and water. We don’t have filter coffee so our long blacks all have a crema, although it’s not cream it’s-”
Customer: “DO YOU THINK I DON’T KNOW THIS DIFFERENCE BETWEEN BLACK AND WHITE YOU DUMB BITCH!!??”

As he says this he tosses the hot coffee all over me. My manager had heard yelling and come to investigate in time to witness this, and chased him out of the store. This is my first angry customer ever, so I was absolutely terrified!

In our store, dollar off coupons always come off before percent off ones. So if you do a post-sale transaction with a dollar off after you had used a percent off coupon, it will affect how much you get back. The math is all laid out on the receipt and the computer figures it out automatically.
Customer: Hi, I forgot to use this $17 coupon.
Me: Okay, I can do a post-sale on the receipt but just so you know, because you had a percent off, it will affect how much you are credited back.
Customer: Okay.
Due to the other coupon she had previously, she would get back $14.45.
Customer: That isn’t correct.
Me: It’s because the percent off coupon has changed. If you would’ve rang this up during the transaction this would’ve equaled out to this price now.
She leaves and comes back still upset with the math. I void out the post-sale, do a return and go to repurchase the item taking her step by step through the math.
Me: Okay, the shirt is $29.99. When I take $17 off it makes it 12.99. After that I take 15% off which takes the total to $11.04. You had originally purchased it for $25.49 and when I credited back the $14.45 you would’ve ended up only paying $11.04 which is what we are going to do now.
Customer: No that’s wrong. I don’t like that math. I’m calling corporate. They’ll fix it. It should be cheaper.
I was with her for 30 minutes trying to talk her through this.

(This happened a few years ago. My Mom, sister, and I were in the drive-thru of a popular Canadian coffee and donut shop (take a guess). So, Mom ordered the drinks. It’s also important to note that my Mom worked night shift in those days, so she was quite tired all the time. This was somewhat how the order went:)

Mom: (orders my drink) … and I’d like a small iced capp. (iced cappuccino) and a small iced cappuccino.

Worker: It’s the same thing…

Mom: (clicks in) Oh, I’m sorry! I’m tired… I work night shift.

(For awhile after that, we kept mocking her, “I’d like a small iced capp. and a small iced cappuccino.” I feel bad for doing doing that now…)

My Aunt is checking out at a clothing store. Mind you, she’s in her fifties, but doesn’t look to be any older than her forties. As she’s checking out, she’s asked if she wants to sign up for the senior discount. Shocked, she replies, “How old do you think I am?” She then finds out that the senior discount, at this particular store, is for people fifty-five and over.

(This is my sister’s story. Whether she shared it on here or not, I don’t know, but I will, anyway…)

My Sister’s Story: When you’re at McDonald’s, grabbing an iced coffee, and someone at the counter asked what the happy meal toy was. The worker said, “A storybook.” The customer was like, “A storybook? What on Earth is that?”

My response: You should submit that on the “Not Always Right” website. If not, I will.
