If I had 2 kuai for each time someone asked me to help out with this or that, I could buy a car.
The OP wasn't asking you specifically. Perhaps you'd be able to buy a car if you adjusted your statement to 'if I had 2 kuai for each time I assumed someone asked me to help out with this or that', and you'd probably finish the car transaction 2 kuai up after
the salesman asked you to sign the bill of sale. Result!
