Unfiltered Story #205631

I am working at an automated self checkout when I hear a commotion at one of the terminals. This usually indicates a problem with the machine but I look and it isn’t giving an error message then I hear this from the couple:
Male Customer: … but that’s 43… (looks at receipt and does mental math) it’s supposed to be 44!
Female Customer: let’s go it’s just a penny.
Male Customer: I’m not leaving without my f****** penny. (Sees me) Make this machine give me my f***** penny!
Me: Sir, please lift your bags and I will. (I open the drawer and pull out the penny.) Have a nice day sir! (He leaves mumbling about the machines stealing from him.)
