1)dont worry too much about this..were the 2 guys in karwa uniform?..u said they gave ur number to the karwa guy..explain urself to the cops if these karwa guys do actually complain..The cops here will hear your side of your story..the guys from karwa are not cops,so screw them..maybe they were trying to hustle you..(if they werent in karwa uniform..u shud have taken a snaps of all the 3 of them with ur phone too..the cops will hear you out and decide..if it does come to that..u cant be fined without any proof..especially if a cop didnt take down ur number..

2)if u were carlifting..(the term you used)avoid,citycentre ;-)..
