While still working as a split driver about 5-6 years ago, I once had a few bundles of temporary plastic fencing for a residential customer. It was shipped in plastic wrap with information on a manufacturers label inside the plastic.
I began to unload it and the customer came running out and said "wait, that may not be necessary". I was perplexed but let him go on. He studies the manufacturers label and says "I hate to do this to you, but I have to refuse these".
I tell him it's no big deal, I just needed to know the reason (IE, didn't order, canceled, etc.) and he tells me "it was made in China, we only buy American made products in this home". I didn't question him because I didn't want to insult him or give him the open door to essentially preach to the choir, but he was serious, and that stuck with me, and it always will.
I try to buy American whenever possible, but it's not as easy as it once was. Even the "domestic" Dodge Ram in my driveway has 20% parts content from either Canada or Mexico in it. Hell, I've owned a whole bunch of cars, and the only car I've ever driven that's 100% American is the 46 year old Pontiac in my garage.
