Tipping is an option but as I said before you can use it as a great example to teach your children a giving spirit. We just budget it into our spending money. 2 Corinthians 9:7-9 Each man should give what he has decided in his heart to give, not relunctantly or under compulsion, for God loves a cheerful giver. And God is able to make all grace abound to you, so that in all things at all times, having all that you need, you will abound in every good work. As it is written; "He has scattered abroad his gifts to the poor; his righteousness endures forever." I think these verses in the bible even apply to tipping as not a requirement but doing what you decide in your heart and being cheerful about it.
