I have been helping Jerry at store a lot lately and I have not had any problems - until today. For some reason, I have been giving the wrong amount in change. This morning our neighbor bought a Sprite 1.5 L and I think that I might have given him 10 pesos more in change. Just now, a guy bought a small bottle of Sparkle (it's like 7 Up) and I gave him 8 pesos less in change! My husband is sitting beside me trying not to ream me out but I know he is upset...ha ha...gotta be more careful next time.
