This should be everyone's watchword all day, everyday. Being polite and friendly can really go a long way in solving a lot of problems. The staffs working in the CS section are human beings too and being polite will definitely have a positive impact on them. For me, it has helped me gain faster resolve to my tickets as the person who handles my ticket will surely want to help me. I ensure that I greet, ask about their well being, commend them for their tireless efforts in making Fiverr a great marketplace for buyers and sellers. I also ensure that I frequently use the word PLEASE and THANK YOU.
