There is a point to the following story, if you'd like just skip the conversation, though it does give perspective.
The other day I was picking up lunch at my college. Since it's a buffet style you pretty much just grab what you want and go, and on this particular occasion I decided to get some pasta, but after I had already grabbed a bowl I found out that they had run out of parmesan cheese. I saw one of the chef's behind the counter, and our conversation went like this:
"Hola amigo! I was wondering if you could help me?"
"What you say?"
"Um, hi friend, I was wondering if you could help me?"
"Listen, don't call me 'amigo' or 'friend', call me sir. Now what do you want?"
"Well I noticed you ran out of parmesan cheese up here, I was wondering if you had any in the back?"
"No." (he didn't bother to check, or even look behind him)
"Okay then, thanks anyways sir." And he turned away without responding.
Once I had finished my meal I walked by and saw the parmesan container full.
Now, I realize that this may seem pretty small, but it's connected to a larger point that I really have a problem with: assumptions about respect. I addressed the man as 'amigo' and 'friend', two words that carry no insult, and carry no lack of respect, yet he threw it back in my face and refused me service. Respect is not something that you're entitled to, it's something you earn, and with his actions he has lost mine.
That's one of many problems in society today (in my humble opinion). We all seem to think that we're entitled to things we're not. If you show up to class, you get an "A". Wrong. The bare minimum effort deserves the bare minimum passing grade: "D-". If you're a manager your employees should respect you. Wrong again: although people pretend to show respect to their higher ups, often it is just that: pretending. If you prove yourself a good manager then you've earned respect, just holding the title doesn't mean you deserve it.
Getting back to the chef: I work in a convenience store, and in many ways our jobs overlap. We both have to deal with large quantities of the public, and the majority of the public assumes that we're working at such a lowly position because there's something essentially flawed with us, that we deserve nothing more, and so we're treated like crap. If someone comes up to you and asks politely and respectfully for help, you should do the same, not only because you as a decent person should, but also because it's part of the damn reason they pay you. Do I have cranky days at work? Certainly. Do I let them effect the face I give customers? No. There's a pretty high chance that someone would complain and I'd have to pay for it later on.
Rant mode over, thank you for putting up with me
