Ako rin, if ever someone asks me if I'll leave the slot I'll just say " opo, pero may iniintay pa ako mga x minutes siguro. " if ever I'm waiting for somebody so that the other driver can either choose kung maghahanap siya ng iba or maghihintay nalang. If wala naman, I'll leave the slot immediately. Hindi yung tipong sinusulit mo pa bayad mo dun sa covered parking. lol.
