a little backstory: i work at a mcdonalds, have been there for about 6 months. i typically work the kitchen, but my manager decided that i needed to start learning how to take orders and working drive-thru. at the time, it was my second day taking drive-thru orders so i had some idea of what i was doing, but had still to get a rhythm going (when i worked kitchen, i got a "rhythm" where i could do the work without really thinking too much). also, i typically forget some practices that we have to adhere to (smiling whenever we're at the counter). you should note that i'm a fairly short guy, around 5 feet tall at most. these facts will be important later. for whatever reason, when i walked in to start my shift, i noticed the hello kitty toys in the display and the hello kitty design on the happy meal box, so i assumed that we still had the toy.

this leads me to when i was taking orders at the drive thru. a car (nice asian brand, maybe a kia) stopped to order. she ordered a typical meal, one sandwich for herself, and a kids meal for her daughter. she asked what toys we had for girls, and being too lazy to check, i said that we had the hello kitty toys (we had the creepy furby toys). after she paid, she went on her way. a few minutes later she stormed into the dining area of the store, little girl in tow.

"i want to speak with the fucking drive-thru boy! where is he?"

esmerelda, one of the managers tried to calm her down.

"what's the problem, can i help you?"

"the drive-thru boy? where is he? he fucking lied to me! do you have the hello kitty toys?"

esmerelda checked where we held the happy meal boxes to quickly see if we still had the toys.

"sorry, we don't."

"well can you bring him here, the fucking drive-thru boy?"

i got called up to the front.

"did you tell me that you had the toy? the hello kitty?"

"yes, ma'am."

"did you know that you had none?"

at this point, i was fairly unhappy that i had messed up, and was frowning. i remembered that i had to keep a happy face for customers at all times. i smiled at the wrong time.

"no, ma'am."

"look at that, he's grinning at me. you lying shit!"

i tried to apologize, and i said i'd check the back to see if we still had the toy. 

"you better fucking have that toy. look at my daughter's face, you lied to her on her birthday!"

esmerelda let me go to the back, and i went. we have these sliding, large metal shelves to store our supplies, and i pulled the one over to search for the toy. now, due to my height, i can't really be seen through all the merchandise. as i was looking for the toy, one of my coworkers apparently didn't hear or see me, and pushed one of the shelves. i was between the two shelves and was almost crushed by the two. she must have heard me yelp, and pulled it back. i happened to be pushed forward while i was tiptoeing to reach the higher shelves, since i was short, so i stumbled forward and hit my head on the shelf. so now there's this gash on my forehead, i had a slight headache, and i still hadn't found the toy. i walked back to the front and apologized that we had none in the back either. 

as i was walking back, i heard the woman tell esmerelda, "you better fire his punk ass! he messed up my daughter's birthday."

"we'll do what we can." i walk up. "teban100, what happened to your face?"

"look, he can't even fucking take care of himself, just fire him! you'll do customers like me and yourselves a favor." she looks at me. "fucking apologize to my daughter. you ruined her birthday."

again, with the smiling. i looked at the girl and smiled (to try to be nice). the gash was worse than i thought, because i might have looked like a creepy clown or something horrible to that child. smiling didn't help, and before i got to say anything, the little girl just started to cry. 

"look at what you did to my daughter! we're never getting food from here again."

i guess the woman grew tired of the situation. "can you just give me a toy that isn't as shitty as this one?" she held up the despicable furby.

we got her a nicer looking boy toy, one of those cars for max turbo or something. the girl stopped crying, and immediately liked the toy. figures. 

they left.

esmerelda laughed a little as the woman was out of earshot. 
"wow, teban100. she's crazy, huh? let's see if i can get a bandage for that cut."

i just got my schedule for the next two weeks and i'm reassigned to the kitchen again. i guess i won't be doing drive-thru for a while now.
