"I don't want to discuss my personal tipping policy but I feel that it is not my responsibilty to pay the wages for someone not in my employment. I feel that the employers of service providing business should up their prices and pay there employees a sufficient wage so they don't have to prostitute themselves in order to subsidize their minimum wage. Needless to say this will never come about but I'm pretty sure that many service industry people would go along with this thought when they reach retirment age and are dependedent on Social Security as a supplementary income which is paid out in direct proportion to the amount paid in by ones employer and himself."

It came about in the UK as I explained elsewhere.
Many establishments that dont/cant accept tips have a charity box at the paypoint/checkout or whatever.
