AM/PM Scams Mojave, California

Dont like your Money? I was a regular customer  dumping thousands into this store yearly untill i had seen Carlos the graveyard shift regular ring me up and input 10$ where 20$ would have gone because i got a few things, i said something about it and he acted confused and tried to give me a dollar that was a month ago .i have now noticed 50% of the employees run similar scams charging for things that just arent there, if youre a regular joe dont shop there, and i advise any agency dont buy only gas and dont use a card.. card is useless they cant scam it....id wear a wire for sure if it meant exposing them and getting it restaffed..sure theyre friendly but...its not okay
