Need a gatekeeper

After a week assignment in Park Lane Hotel, I went back to my office and found that the door was automatically locked. It was required as my office is an International Organization.

now, to enter the office, we need to use access cards which are given to some staffs including me. It is pity that not all the people in the office get the card. So, many times those who want to enter the office, have to knock the door.
Therefore, I think my office needs a gatekeeper, hahaha because the security must feel tired to open then close the door for those who get no cards.
