The way I handle tips, is to hand the money to the person I feel 'deserves' the tip.. if I put a 'tip' on my tab it's for the establishment, they share it.. if one person stands out, the cash goes in their pocket.. I don't work in a 'tip' environment, and don't expect em..(I'm paid for what I do)..
Precious metals are an investment, based on speculation, like any other investment..
Stocks, bonds, etf's, are paper(like money).. physical precious metal, if you bought it at the right time, is definitely a good hedge..
And for transparency, I also have paper investments in at least a few of the corp's
