I work for contract, which means I have to beg for my check every time I'm supposed to get it which can take a week or more sometimes. Long story short, I rolled pennies and tried buy an item as amazingly expensive as sugar and they refused to accept it.
The clerks acted like I was some sort of criminal and held the line up while they got into a group and consulted about me paying for sugar with pennies. Discrimination was part of the issue, as 90% of the workers at this particular walmart are of a different ethnicity than myself. I think this excuse to refuse my patronage has given them what they want. I will make sure I go where people look like me so I can be treated like a human being.
