poor pricing process

So you pay R63 for 5 pieces with chips at KFC. Heaven forbid you don't eat chips, You then get charged R70 for 5 pieces without chips. Biggest Food chain in the country and probably the world.... C'mon guys!!! You'd think one of you many execs could do simple maths. But wait there's more!!! Bet you I get the email response about 5 x R13.90 like the cashiers so willingly points out as if I'm as ******** as KFC. Hopefully someone in the great organisation can answer my query without antagonizing me.
