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.
Have synthesizers, will travel...
