Time Management~~

I hate people to be late for appointments...i mean whats the purpose of making one if you cant keep it..its just like promises...when we agree to meet on Mon 2 pm...means its confirmed.. its just respect to reach the place on time or even 10 min earlier..i hate to change time or date..unless something urgent came up...and i dont understand why people can be late when meeting others..even before that they are at home doing nothing..or worst the meeting location is just near their house walking distance... recently i just joined this new company...they say working hours is from 9am - 6pm...ok they say this area will have jam in the morning so the latest you can reach at 9.30..so i take it as its 9am unless really jam..so i plan to go out from my house at 8 am...who knows..i reach at 9am..no one around to open the door!!! i have been trying to reach at 9am for a week le...its pointless waste my time..so i gave up..now i take it as 9.30 than i have to start work. And every time i fixed a appointment with a customer, they will last min ask me to change the date or time... What The Fu*k!! Its really not pro to do this in business!! Pissed me off really... i think its just fu*k up they cant fu*king plan their schedule and please la they are all fu*king adults lei...sure they can plan their time for goodness sake... really i am so angry...time management is really improtant..and time is really priceless..should show some respect for other people's time.
