Because drivers of CDG read names of callers , thus caused CDG
corporate customers cannot get a cab , which their hotline is being
dominated by non-corporate customers .
Callers , which has got a big base of locals holding corporate
cards , has got difficulties in getting cabs , call also need 1
hour , wtf right ?
Whatever Scheme A or Scheme B , same problem .
This is one way to protect their customer's base .
Good move .
