I have to agree with Grumpy Mark on this issue ( 🙂 ).
If you’re selling something, then you’re in the position to offer advice on the product if the customer asks. I can’t stand all the bullshit that surrounds marketing, and when I worked in retail I was always honest about stuff, even if it did mean the odd lost sale. I considered my integrity to be more important than my employer’s profit margins. I regularly had people thanking me for my honesty, and felt I gained more respect from others that way.
Funny; you bike shop bods are often on here moaning about customers not showing you respect and stuff, yet here’s someone seemingly willing to lie to people in order to make money. 🙄
Granted, a lot of retail is about embellishing the truth, selling myths etc, but something like this is akin to deceit, imo.
