Paul, that's kind of you to call me your 'technical guy,' but, in all fairness, I'm one
of your technical guys
As far as Marriages Millers not providing spec sheets to prospective customers... that is absolutely ridiculous. It would be like a car dealership not telling prospective buyers the gas mileage on the models they're selling. It's just horrible business.
I'm well aware that you've been looking for flour suppliers and are quickly running out of options, but, if you did have another company you could deal with, I would tell you to tell MM where to go. They don't deserves anyone's business.
There's a good chance you'll be doing business with these folks, so you can't push the envelope too far, but, if I were you, I would send them a link to this discussion.* They should be made aware that the public is being made aware of this policy and that it reflects incredibly poorly on their company.
*Checking with Peter and/or Steve first to make sure it's alright.
