Milky Lane - advertise one price, just charges 32.6% more without telling you

When you grab a quick ice cream desert at Milky Lane, and the overhead screen says R42.90 for one tub and R52.90 for the other tub.. the total should be under R100....

But the card machine is put down in front of me for R111.80 (R54.90 + 56.90)

When the one item goes from R42.90 on the display to R56.90 on the slip.... (32.6% overcharge)

(i have pics of the display price and the slip)

Makes me want to NOT buy your product again... We were 2 people, imagine a family of 4 or a kids party of 25 and you get fleeced 30% more than you thought you spending
