Typecasting in the industry...

Over the years in my line of work in food service and retail I have been witness to some patterns in both areas. Obviously my experience is a very small percentage of the whole industry but I find it odd that the same similarities hold true from place to place. In restaurants for instance: the chef is the touchiest person you will ever meet, the bartender is an alcoholic, the dishwashers are the hardest working people in the place and never speak English, and the busser that seems stoned all the time is stoned all the time. In retail: the District Manager is either on speed or really just the most wound up person on earth, the management never knows what's going on (I am one of them so I can say that with all humility and honesty), and least one associate is robbing you blind, and the receiver is the second touchiest person you will ever meet. Maybe this is just my experience withing my ten years of watching and remembering...anyone else find this to be true??
On a side note....I HATE INVENTORY!! For the first time in my life I am working for a corporate business that does not use Regis to do its inventory (if you work in retail you know how crazy that is). This is a pain in the ass because we don't have a great inventory system to start with. Our back stock is insane and apparently our customers like to eat price tags because I think we are missing tags on half our merchandise. This means going through everything by hand and writing out tickets. Not fun...plus our scanning day starts at 4a.m. All I can say is there better be free coffee...buckets of it.
Oh and by the way...I am up for a promotion. I should be hearing about it in the next few days so if i get it there will be a very big "Wheehoo!!!" post. If I don't get it there will still be a "Wheehoo!!!" post but with drunken undertones. Cross your fingers.
