One of my favorite meals, when I actually bother to properly cook at home, is one I got from the Protein Power message board years and years ago. Simply called "Steph's Yummy Chicken Stuff", it's basically a dressing mix on chicken, with parmesan cheese baked on top. Excellent and simple.
Well, we have an item on our menu that's basically the same concept--just different dressing and cheese. I'd had that the night before, but I was kind of in the mood for something different Monday night. So I grabbed mayonnaise, salad dressing, and sour cream and mixed up a little bit of topping for the chicken; then I got some shredded parm and gave them both to the cook. I very politely explained what I was after; I said please and thank you. I didn't think it was that big a deal--no southwestern, sub stuff I'd mixed up; no cheddar sub parm; no rice sub veggies. Not high-impact modifiers, honestly. Same processes as what he'd have to do for the regular menu item.
He acted like I wanted him to saw off his own freaking limb! He started throwing things, slamming stuff down, and yelling in Spanish. A few minutes later I came back to the kitchen and he was still bitching, listening off my modifiers at the top of his lungs to the other cook. I got irritated at that point and told him "It's just like the (regular item), it's just different cheese and dressing! What's the big freaking deal!"
He ignored me; I actually thought I was going to have to get Lapdog and ask him to tell the guy to make the food I was paying for! But he eventually put my food up ... only instead of a layer of nicely baked cheese on top, like I wanted and like the regular menu has, and instead of parmesan, I had a pile of slightly melted white cheddar. I was so hungry I just ate it, and it wasn't terrible; but I was pissed that he threw such a fit over it. It wasn't busy; it wasn't late; there was no reason for his tantrum. I didn't realize that asking for two little changes was going to incite such anger.
