Always check your small change and request till slip

Good evening,on the 17 march 2025 i visited Engen garage Nkomo Village in Atteridgeville,i bought snacks to the value of R83.90 then paid with R200 note.The cashier then returned my change as (R116.00), which was meant to be (R116.10) after she gave back my change i then requested for my till slip,she looked surprised ,while waiting for my till slip she then included the outstanding 10 cents which was initially withheld from me.So dear customers please check your change after every purchase every where you buy.This was a reminder to always ask for a till slip in order to can see what was bought vs the amount you paid.The outstanding amount could have bin more,and my question is why cant such places just charge normal streight prices no cents required if their staff constantly dont seem to see the importance of giving us back our brown coins as small change.
