• Engineering students please don't get into the trap if you want core engineering related future in here.
•according to many comments saying less lunch hour ( every bit of second is lunch hour only because you will be on road seeking for car drivers or owners, begging to take the service from you and in return you will give pamphlet and coupons which is useless for customers and in return you may get some abusive feedback.
