Quoted from Bryan_Kelly:Let me use another example. I have friends who are thrifty. Nothing wrong with thrifty. Thrifty just means you're careful with your money.
Then I have friends who are tight. And I mean downright TIGHT. Tighter than a bull's ass in fly time, as my father in law used to say. I don't like tight people. I could tell you stories all day about my one TIGHT friend but I'll just give you one and I think you'll understand.
Bill and Frank, (not real names) place one order with Pinball Life to save on shipping. Bill's portion of the order is $30 and Frank's is $70. Shipping was $10 so you would think they're going to split it and each pay $5. Oh, but you'd be wrong! Order comes to Frank's house and when Bill shows up to pick up his portion, he hands Frank $33. That's right. Bill feels he only owes 30% of the shipping because his portion of the order was only 30%.
I will say Bill is not wrong, but that's just a dick move in my eyes and so is trying to get a shit ton more for an item than it's worth.
Actually the shipping cost is determined by weight at the post office, so the correct way to split it would be for Bill to bring over a digital scale and weigh each of their items and apportion it that way. That's how I would have done it. (Unless of course I would have saved money by dividing it the way they did.)
