Thank you for the reply and advice, Adjusterjack. I will definitely be calling and chasing after the lawyer (?) to pay the fine as soon as possible.

Just some follow up questions:
1) Say that I want to apply for a job as an accountant or manager in the future (not in retail, maybe like hotels, restaurants, or accounting firms), will it still show up?
2) The LP did say I will be on their (I assumed Walmart) database; is it safe to assume this incident won't show up in any other public/private database other than retail?
3) Will my name be forever in the retail database, or will it ever "expire"?

My apology for the unprofessional terms. I am still a nervous wreck after the incident and have no previous law background/experience.
