Service at McDonalds Cavalier Centre, Cape Town

I just went to McDonalds here in Cabalier Centre Belhar and to my dismay I discovered that they don't accept scan payments. Living a distance from the store, I had to ask a couple who was at the store to pay as I didn't have my bankcard with me, only my cellphone. So it was a bit of an embarrassment as I couldn't understand why this McDonalds don't have a scan facility, I mean, a USA company and they lacking the technology????
