Not so wise..
Scooter..
So in about a few years from now, you're sitting in that nice business class towards the Seychelles for a well deserved holiday, when suddenly for some reason the Captain announces on the PA that you won't be able to get to SEZ, but no worries... you will have a free night in the New York of the Middle East. Landing in Dubai will be in about 45 minutes.. And that's where you start sweating really hard!!!
No, seriously, if leaving, you better do it the official way. Not only will you be able to go places without looking over your shoulder all the time, but also, you won't make life harder for the colleagues you leave behind.
