The preceding poignantly pithy phrase points profoundly at the (ok alliteration over) subject material for this particular post (sorry, I'm done I swear).
Now, I have worked in retail. I remember the experience. There are a few elements that make retail hell on earth:
Stupid Questions -
Customer - "Do you work here?"
Employee - "No, I just wear the company shirts to throw you off, SUCKAH!"
Unfounded Anger -
Customer - "Where are your veggie burgers!?"
Employee - "Sir, we don't serve food."
Customer - "Why NOT!? AREN'T YOU SUPPOSED TO PROVDE VEGETARIAN OPTIONS!!!???"
Employee - "We're a record store…"
Price Hagglers -
Customer - "How much for this shirt?"
Employee - "Seventeen dollars."
Customer - "I'll give you sixteen…"
Employee - "Tell you what! You give me eighteen and I'll give you a dollar in change! It will be like you made money."
OR, the ever popular.
Customer - "This doesn't have a price tag on it… I guess it's free"
Employee - "HA-HAAAAAAA… You didn't tell me you were the reincarnation of Andy Kaufmann you sly devil! That was so original, I'll even throw in a shirt for sixteen dollars!"
