Last Friday, i had to travel from trvl to cbe.. I planned to reach ers by 56392 QLN-ERS psngr n get 12678 SBC ICE from der.. My friend reached der n took a UR ticket of rs.80 to CBE for me n gave it to me.. Unfortunately i cudnt get ICE cz psngr was late n ICE departed, then i boarded 12076 JS to TCR , TTE collected rs. 40 to convert it to JS ticket... Anyone know what is that '40' ? How it comes to 40..? Is it diff. Amt?
