Assuming you did not have "about 50 other stores to go to." There's tons of people who wouldn't have that option. People who do things the right and honest way. But we'll have to leave bygones as bygones because of what I made bold. Clearly we have different morals. 1 pair out of 500K or 5,000K, it's still wrong.
And because I hear and see this entirely too often and it is a pet peeve of mine, the correct phrase is "I couldn't care less." You are implying you still do care.
Good luck getting your pair bro.
