In the end, people are just animals. Best to avoid getting too attached to them.
Think of the customers - most of them want to get their honeysuckle and get out. A few will act like shits, but it's rare to deal with them on a long-term basis.
When I worked in retail (graveyard shift stocking peon) I hated my coworkers more than anything. It usually is the coworkers and horrible managers.
If you're in a position where social interaction is common place, you do realize that management or troublemaking coworkers will deliberately send customers to honeysuckle on you, in order to put you in your place? It's sick but society has agreed to make this standard operating procedure. It might sound bad to focus on things which you can't control, but you should know them rather than ignore the elephant in the room.
Then again I don't know the details, maybe you are in management and have to deal with disrespectful peons (and I know some managers put up with a lot of undeserved honeysuckle from their underlings, and sniping from their equals/superiors).
With the world being what it is, it's not like someone can just "get a different job" - especially now with the crunch for positions. This society (America, Canuckia, and the Eurozone all together) are in for some really harsh times. Something like over 30% of people are unemployed, underemployed, or living entirely on public assistance. It sounds like a rightist scare tactic and of course it's being used for that, but there was truth when Mittens brought up the 47% thing - a lot of people are poor and have to live with what scraps they can get.
