Even the HK based crew dislike their YVR counterparts:

For those that don't read Chinese basically a HKG based crew complaining about the attitude of YVR crew:

記得一次令我不得不O嘴既係喺一次after flight時發生的。HK base啲菇慣性同同事講thank you for the flight, 係基本禮貌！那一次，有幾個HK男菇幫其他菇喺行李輸送帶度取行李 ，我都順帶喺取回自己行李時大聲向各位講聲唔該晒同thank you for the flight之後拜拜 ! 一個 YVR base 既女purser 走黎同我講： 乜你地啲HK base 甘鐘意乜都say thank you 架啫？！
我有少少咢然地答： 禮貌黎㗎啫！(心諗畢竟人地真係幫咗你，而且班機都飛得幾開心吖！)
佢竟然仲問：咁我地無講即係話我地無禮貌啦！？！？
我好想答 係 ！你地連幾基本禮貌都無，點解公司會請埋你d咁既人……不過最後我都係笑笑口講聲拜拜走了！ 啤！！
