I ever worked as a tour guide. One day I saw advertisement in the newspaper. I rang up the company, but I was given the job immediate. They asked me to take a tour around the city next morning. The
manager just told me to say anything that I could think about the city. My first tour is terrible. The old bus was not air-conditioned, because it was the middle of summer. It was uncomfortable inside the bus. The
tourist soon became very hot and angry. I owned a very hard time. I stayed there for a few weeks, and
then left and joined in a better company.
