Perhaps you might consider yourself an ambassador for Christ. If so, you should never ever offend anyone by walking on their cultural traditions. That is the attitude Missionaries have.
Also, bowing is just part of their cultural tradition. I think it helps me as a Christian to practice the humility, and no ego, in bowing. Showing respect where respect is due. I rather like it. Kinda wish it was part of western culture.
Also, God wants worship out of love. He's had his fill of empty respectfull patronization. Worship God with all your heart, all your mind, and all your soul. Love God so much that you worship him. That is the kind of worship God wants. And yes, he wants it all to himself.
