What if I start pocketing about 90% of the cash people hand me at work?
What are you thinking? Do you want to get fired and destroy your reputation?
I work at a retail store where people come to buy daily life stuff.
That is not a good thing to do. It is wrong to steal from your place of work. This will not help you with future job opportunities.
Nah. I'm going to do that Saturday. I have some large bills to pay.
Stealing is not a financial plan; how long do you think it will take for your employers discover your register is 90% short? You'll be fired, if not arrested. Instead, take a course in personal budget management.
