I'll still will never forget the guy who said he was "going to cut me" at my last retail job. Oh memories.
I understand what you mean by customer service getting paid for. I remember the lists of *needs to be done yesterday* crap I was left to do in addition to customer service. Let's see, you want me to supervise the staff, clean the store, feed all the animals, recover the shelf stock, work the back stock, set a new planogram, and I am the only one who isn't on a register?
Can I get a wand?
Then there were the customers themselves.
Someone brings me a zip lock full of kibble and wants to know if we carry their brand of which they can't remember the brand, price, bag color, ingredients, or if it was for a dog or a cat. Spending 20 minutes with a guy telling him about getting better dog food only to watch him grab the bag of Kibbles N Bits on his way to the register. The kid who wants to hold every soft furry thing we have in the store. The guy who insists the rats are sick when they are just sleeping in a pile. The guy who thinks that I'm somehow a vet or wants to know where we keep the Rx painkillers for their pit who clearly has a headache. The guy who brings me in their dogs stool samples to identify what kind of worms they have.
*facepalm*
Then there is the company. Nothing builds insanity faster than following the P&P pages for a big corporation.
We get ferrets so young they don't have teeth yet but they meet the P&P for weight therefore the company sees nothing wrong with that.
My manager openly discriminates against protected classes while hiring so I report him to HR. The company decided to transfer me instead to solve the conflict without asking me.
Our water kills goldfish but rather than not ordering goldfish they tell us to order more because we can't be out of stock.
It had been 4 months since the cricket bins had been clean but there were no hours allotted to clean the cricket bins therefore it needed to wait longer because we were short on hours that week.
