I hate it when they screw up my order at the drive through. Don't get me wrong, I'm not one of those super picky people that order no onion, and freak if there's an onion on it. I will throw it in the garbage, and proceed devouring my burger, we're all human after all. But, if I order a double cheesebuger and fries, and get back to work to find;
A: a fish sandwich, or;
B: a double cheeseburger that's either so cold or so old the cheese isn't even melted, and my fries are the same, I'm not going to be happy. I realize you probably hate your job, and it's not what you thought a job would be or where your saw yourself in life. But, you know what? I've done it, it's honest work and there's nothing wrong with it, it's not THAT bad. And it's definitely not rocket science building a cheeseburger. Soldering, for example is way harder.
I hate rude, self absorbed people in general, even if they're family. Is it really so important to get in line a millisecond before me or get that last item on the endcap, even though there's hundreds more to buy in the aisle? Or to not even acknowledge that there are other people in the store or business, literally ignoring everyone around you with your uppity attitude.
And worst of all IMHO, don't comlain about your gift or show dissapointment. Somebody worked hard to pay for that item, whether it's what you really wanted or not. I saw this scenario play out a couple year's ago, and I wasn't the buying or receiving party, but the buyer was crushed obviously. Nobody wants to feel like they picked out a crappy gift, and you don't want to be the person that makes someone feel that way if you really think about it.
