I have a tipping story about Australia. I was there for two weeks on vacation and took a taxi to the airport to leave the country. The bill came to around $40 Australian and I had 50 Australian dollars. I told the cabbie to keep the change. He almost wrestled me to the ground to give it back. I told him I was leaving Australia and had no reason for 10 Australian dollars and the fees to convert it to US dollars would take 1/2 the money. He finally kept it but I honestly think I hurt his feelings and insulted him by making him take a tip.
