You got that right.
Being in the machining business, with only 2 people in the shop, phone calls just take up too much time some days. Email is so much better being I can reply when I get to it, rather than talk on a phone in the middle of a job that needs 100% of my attention, that someone is paying me to do.
I'd expect nothing more from someone else in a small busy business.
As soon as I have the cash, I plan on sending some work his way.
