its actually that deshi and arab muslims are totally unpunctual. (or they are punctual fanatics and they drive everybody bonkers).
according to Einstein time lasts longer if you are moving really fast. well, actually you don't have to be moving at near the speed of light to turn 5 minutes into 45 minutes. you just have to go to a muslim country
ps: for pedants -- by time lasting longer, i mean from the point of view of of the static observer. i.e what is 5 minutes in a moving frame turns out to 45 minutes in the static frame
