Jordan Vietnam Etiquette

Throughout my whole day i was thinking of how to get back to my hotel after my cyclo tour. I didn't have a phone so I could not call a taxi or my friend. I then realized i could just call over a taxi by calling them over with my hands and fingers. I kept on waving to taxi cars and cyclos to come pick me up, but they would not come. It was getting late and I was tired. I was thinking why are the taxi drivers so mean and rude here in Vietnam. My friend was at our hotel and I knew he would start to worry if I didn't come to the hotel soon. I really needed to find a ride quick. I looked in my Hanoi handbook to see the quickest route to walk back. I caught my eye on a part of the handbook that said "Etiquette" and the first rule was "never point to someone and call them over." I thought this section was not important, but I realized I should have learned what was respectful and disrespectful to do in Hanoi, Vietnam. From my mistakes that I made, I had a long walk home.
