And untrained / not fully trained sales people are lethal.
They get nervous - desperate to secure a sale and then the verbal poop just keeps on spilling out!

That's why it's critical to make sure you get them to stop before they begin.

(I also over-egg my adhesive and grout requirements - customers are thrilled when they can return stuff for a refund - not so happy to cough up extra)

I hear; I forget
I see; I remember
I do; and I understand.
