sometimes I play as a mechanic so ppl ask for E-repairing and when u go to fix their engine u will be frozen and can't move.
this will not be a problem when u are innocent or ticketable but when u have 2 wanted level or more, u can get killed or arrested easily.
one day I was MW and have repaired cops Engine car cuz I want to see their reaction, Fortunately, since today no one had caused a problem for me but I know one day I will get rekt by someone when I am repairing an engine.
if u canceled E-repairing, part or all of the money should back to the driver.
if there be a way when mechanic canceled his job driver could drive his car, for example, if the mechanic cancels his job in the middle, the driver drives his car with a half health car.
if u have a better idea share it here.
