beast sap...no need to APPROACH THEM they will take what they want...., From my friend's words - "the driving 'Ustad' will simply take your phone and call his buddies in the home country or transfer your call credits to his phone or if your phone does not have balance or you 'forgot' to take phone, he will ask you to bring Hala card for next day, if it is his tea time he will lead you to good hotel and both of you will have a good time with food and ask you follow him to car after paying the bil... if you hesitates your driving class will end up in driving school compound itself".
but Karwa is very good, from my experience (5yrs old) and from some of my friends, there is no Goodies..... present status i don't know...
