Not at work, by my riding instructor and her husband are self-employed in a different field, and are perpetually broke, despite being in their 50's. So she and I have been adding alfalfa cubes to our horses' rations, and started talking about splitting a ton, so I checked Craigslist and good quality hay is available for $180 per ton. She said "Oh, the cubes aren't bad, only $13.xx per bag." I pointed out that at 40# per bag, that came up to almost $680 per ton, and she had a sudden blank look on her face, then said "But the bag lasts me like a month" to which pointed out that she must be feeding just over a pound, which is not enough to have any nutritional benefit for a 1,300 pound horse, and again the blank look. She's a great person, and seems to be really happy with life, and generally frugal, but I can definitely see that she doesn't do many calculations, and could probably be living less paycheck-to-paycheck with a little more analysis of where the money goes.
