As for AP trips ..... $3-$5 surcharge , if reasonable distance , they will have my normal service of unloading of luggages .
As for destinations like Pasir Ris , Tampines , Changi , Bedok , if not given any perks , they have to self service .
Maybe Uncle me good mood , they stands a chance .
If not , self service .
Anything above $1 tippings , then will see me open my door , if not , u'll see me sending sms more likely after collecting taxi fare .
