I take it you haven't worked in retail?
I find your post quite patronising. If retail staff were 'better trained' in customer service skills, then there'd be less abuse and rudeness from customers? Are you kidding me?
I've worked in retail (still do unfortunately, but I'm hoping to change jobs) and I work with a great team of people who are always pleasant and. polite to customers, as am I. But, we still get quite a lot of abuse, more so in the last few years.
Most people are nice, but the odd few customers are hellish, no matter how polite and helpful you are to them. That's a fact, so please don't assume that retail staff are at fault for receiving abuse if they've not been 'trained' in customer service skills.
I work for a well known company, and for what it's worth, we DO receive training on all sorts of things, including how to try to diffuse a difficult situation, and I imagine most other companies provide training too. However, when dealing with some customers, nothing will stop them being abusive if they want to be.
The other week for example, I heard a young boy who I know is only about 14 tell his mum in the queue that he wanted a certain kind of vape. His mum then approached me at the till and asked me for the vape he'd described. I said that I was sorry but I wasn't able to serve her with it as I knew it was for her son and he was underage.
The mum never even tried to hide the fact she was buying it for him, and said to me 'so what, I'm his mum and if I want to buy it for him I will'
I explained politely that it was against the law even for her to buy an age restricted product for someone under the age of 18, and because I wouldn't bow down to her demand, she called me a 'fucking cunt' , and so did her underage son, then she grabbed the other items she had on the counter (which she hadn't paid for), said she 'wasn't paying for them' and walked out the shop.
So she wasn't only abusive, but stole items too.
So please tell me, where did I go wrong that I deserved this abuse?
Should I have just given her what she asked for and lost my job for knowingly selling an age restricted item to a minor?
This is just ONE example of abuse we get. No amount of training in customer service skills will stop people being abusive. They are abusive because they believe they can get away with it, nothing more.
I imagine you may reply with something like, 'obviously retail staff will always get some arsehole who is extremely vile, but they wouldn't get as much abuse from the general public if they themselves had good communication skills with the customers'
This is where I believe you'd be wrong, I believe that nearly all customers who are abusive and treat retail workers like shit, do so even when they've been treated properly.
