To scramble above post a bit, but not too much...
If you did that in my shop, you would be standing by yourself as I would have laughed at you and walked away.Aside of that, I understand and agree with richopp's views.
YOUR bad behavior in my shop would have resulted in you leaving with nothing.
We "fired" customers every year at xmas--idiots...
That is what we wanted, so that is the business plan we executed.
Happened a lot more than I thought, which is one reason I sold the shop.
I am amazed at the lack of business intelligence so far in this thread.
