Maplin attracts a lot of 'older' not really tech savvy sort of people now. It's people like these that I and my colleagues had to pounce on and get as much out of them, including up sales on installs and services etc. Personally I use to do the opposite though and just be completely honest and give correct advice and point them to other places that were cheaper ie. HDMI cables. Didn't look good on my sales targets mind you.
As for electrical components, the company doesn't make hardly any profit on. So basically we'd just give resisters, LEDs etc etc away for nothing.
Also expecting colleagues to know every product and know everything about what it can do was not even funny and was a joke for minimum wage.
Hated the place and as such, it's their own fault.
