Let's compare this to the recent BJ olympics:
There was overwhelming response from all over the country (and some foreign countries) to volunteer for the event. I applied too but was not selected
The volunteers were given 2 full sets of (I think Nike) sports suits plus shoes
They were given MacD's vouchers.
Free transport provided to bring them to the stadiums. They were also issued a pass for free public transport (bus and MRT) 24/7 throughout the whole event. My neighbour told me she was given CNY20 a day for road marshalling.
That's enough to cover a decent meal at small restaurants or fast food.
They will be given a volunteer certificate at the end of the event - something that will add points to their academic records and also CV. They will have an advantage in job interviews as employers recognise this cert as well.
In conclusion: You get a bunch of real volunteers that give their heart and soul to the event.
