How absolutely weak can a person get?

How weak can a person get? I mean, seriously, what gives anybody the right to be idiotic and ignorant just to get free food. A man called in an order yesterday and came in and got it. I was the one to mark the sandwich bags. He came back and had his receipt and two sandwiches with him. He pointed to two specific sandwiches on the receipt and told me that I gave him the wrong sandwiches. Yet, the sandwich bags clearly showed that this man was wrong. So, instead of just giving him free food, I explained to him how he, in fact, did have the correct sandwiches. I stayed calm throughout and would've even explained it once more before showing any kind of suppressed rage. Yet, he insisted on getting free food. So, I asked if he had even opened it up and looked, because doing that would have clearly shown him how wrong he was. His response was, "You know, I'm good friends with Ned. I'll just give him a call." How weak is that? Why can't this guy be educated enough to stop, think it through, and talk it out? It's ridiculous that he tattled on me like my gay nieces and nephews. I just thought that adults didn't do that. I mean, seriously, how weak do you have to be to not be competent enough to use a simple process of elimination to figure out that you're about to make yourself look like an idiot and put someone else's self-esteem down for another good 2 weeks.

Ned called the shop later and told me that I was wrong and I shouldn't have questioned the man. But, I hate that he called Ned. Ned is irrational and refuses to listen to the other side of the story. Brian, on the other hand, would've at least heard me out and then told me that I was wrong.

I hate how everything we learn about always being on time and thinking things through and following the rules never is true. It's ridiculous. There are people that didn't graduate high school and are making more money than I could ever dream of making. I hate this world.
