曾經試打去廿幾間 Lettings Agency 登記 property viewing, 佢叫 Cat仔留 Email 因為 Cat仔為咗縮短自己個 email, 自己開咗個好短嘅 domain name 再開 email hosting: stephy@[domain].hk 廿幾間 Agency 有超過15間一聽到 stephy@[domain].hk 就問: 後面係唔係還有 gmail.com Cat仔表示: 非也, stephy@[domain].hk is the full email address already... It's format is valid...... 然後對方就會堅持 This is not a proper email address, it should end by gmail.com [字數限制, 下文見 comment]
