I have extensive retail and wholesale sales experience in the music products industry. I enjoy seeing how other retail businesses work, or don't work, more times than not.
Any salesperson worth their salt knows you don't get the sale without asking for it.
I do a lot of apartment shops each year, and in the past I have done more cellphone sales presentations than any human should have to endure in multiple lifetimes. Unfortunately, I'm almost shocked when someone tries to close me, it happens so infrequently.
