Having worked in retail I can honestly say that 99% of the rotating things cashiers and staff do, do because they have to! Failure to do it results in everything from a telling off to sacking depending on the company!
We used to have to ask at the tills if customers would like to add 50p for the chosen charity. I refused after being shouted at for ten minutes straight by a customer because of it.
Asking if you need help-stalking you around the shop. I was disciplined because I was on my knees half crawled into a shelf space trying to retrieve fallen stock when a mystery shopper asked me where something was. From my location I verbally directed her to it. Next day pulled in because I should have climbed out of the shelf to physically walk her to the item (it was about 3 metres away)
I no longer work in retail but my list of things I hate about customers is at least 3 times as long as my list about retail 😂)
Talking on phones whilst being served, not even acknowledging a hello or thank you, dumping change on the tills, accosting me to ask question whilst I’m outside clearly on my break, actually accosting me down my local pub on a Saturday to ask when his delivery was coming, the constant abuse and rudeness, the list goes on and on. Retail makes you realise what a horrible breed the human race is!
